Abstract
Kinetic analysis of polyesterification reactions using Lewis-acidic metal catalysts have been performed. While Sn-based catalysts are superior to Ti-based catalysts under neat polycondensation conditions (high [H2O]), the result is inverted under azeotropic conditions (low [H2O]). These findings show that the catalytic activity is crucially determined by the robustness of the catalyst against hydrolytic degradation. Kinetic studies of Lewis acidic metal-catalyzed polyesterification reactions unveiled that titanium-based catalyst are prone to hydrolytic degradation, while n-BuSnOOH proved to be a robust catalyst.![]()

Abstract
Monoalkyltin(iv) complexes are well-known catalysts for esterification reactions and polyester formation, yet the mode of operation of these Lewis acidic complexes is still unknown. Here, we report on mechanistic studies of n-butylstannoic acid in stoichiometric and catalytic reactions, analyzed by NMR, IR and MS techniques. While the chemistry of n-butyltin(iv) carboxylates is dominated by formation of multinuclear tin assemblies, we found that under catalytically relevant conditions only monomeric n-BuSn(OAc)3 and dimeric (n-BuSnOAc2OEt)2 are present. Density functional theory (DFT) calculations provide support for a mononuclear mechanism, where n-BuSn(OAc)3 and dimeric (n-BuSnOAc2OEt)2 are regarded as off-cycle species, and suggest that carbon-oxygen bond breaking is the rate-determining step.

Abstract
![]()
1-Hexene
is an important α-olefin for polyethylene production
and is produced from ethene. Recent developments in the α-olefin
industry have led to the successful commercialization of ethene trimerization
catalysts. An important industrially applied ethene trimerization
system uses a mixture of chromium 2-ethylhexanoate, AlEt3, AlEt2Cl, and 2,5-dimethylpyrrole (DMP). Here, we have
studied the activation of this system using catalytic and spectroscopic
experiments (XAS, EPR, and UV–vis) under conditions employed
in industry. First, chromium 2-ethylhexanoate was prepared and characterized
to be [Cr3O(RCO2)6(H2O)3]Cl. Next, the activation of chromium 2-ethylhexanoate with
AlEt3, AlEt2Cl, and DMP was studied, showing
immediate reduction (<5 ms) of the trinuclear Cr(III) carboxylate
and formation of a neutral polynuclear Cr(II) carboxylate complex.
Over time, this Cr(II) carboxylate complex is partially converted
into a chloro-bridged dinuclear Cr(II) pyrrolyl complex. In cyclohexane,
small quantities of an unknown Cr(I) complex (∼1% after 1 h)
are observed, while in toluene, the quantity of Cr(I) is much higher
(∼23% after 1 h). This is due to the formation of cationic
bis(tolyl)Cr(I) complexes, which likely leads to the observed inferior
performance using toluene as the reaction solvent. Catalytic studies
allow us to exclude some of the observed Cr(I) and Cr(II) complexes
as the active species in this catalytic system. Using this combination
of techniques, we have been able to structurally characterize complexes
of this selective Cr-catalyzed trimerization system under conditions
which are employed in industry.

The novel tridentate
PNNOH pincer ligand LH features a reactive 2-hydroxypyridine functionality
as well as a bipyridyl-methylphosphine skeleton for meridional coordination.
This proton-responsive ligand coordinates in a straightforward manner
to RuCl(CO)(H)(PPh3)3 to generate complex 1. The methoxy-protected analogue LMe was also coordinated to Ru(II) for comparison. Both
species have been crystallographically characterized. Site-selective
deprotonation of the 2-hydroxypyridine functionality to give 1′ was achieved using both mild (DBU) and strong bases
(KOtBu and KHMDS), with no sign of involvement of the phosphinomethyl
side arm that was previously established as the reactive fragment.
Complex 1′ is catalytically active in the dehydrogenation
of formic acid to generate CO-free hydrogen in three consecutive runs
as well as for the dehydrogenative coupling of alcohols, giving high
conversions to different esters and outperforming structurally related
PNN ligands lacking the NOH fragment. DFT calculations
suggest more favorable release of H2 through reversible
reactivity of the hydroxypyridine functionality relative to the phosphinomethyl
side arm.

Abstract
The reduction of esters and carboxylic acids to alcohols is a highly relevant conversion for the pharmaceutical and fine-chemical industries and for biomass conversion. It is commonly performed using stoichiometric reagents, and the catalytic hydrogenation of the acids previously required precious metals. Here we report the homogeneously catalyzed hydrogenation of carboxylic acids to alcohols using earth-abundant cobalt. This system, which pairs Co(BF4)2·6H2O with a tridentate phosphine ligand, can reduce a wide range of esters and carboxylic acids under relatively mild conditions (100°C, 80 bar H2) and reaches turnover numbers of up to 8000.
