Radical Esterification of Unactivated Alkenes Using Formate as Carbonyl Source

In recent years, methyl formate has received considerable attention as an ideal and green C1 building block to synthesize carboxylic esters. However, examples of a one-step route to esters with one-carbon elongation using methyl formate as a source of methoxycarbonyl radical are still rare. Herein, we present peroxide-induced radical carbonylation of N-(2-methylallyl)benzamides with methyl formate as the precursor of methoxycarbonyl radical and RuCl₃ as catalyst, affording a series of biologically valuable 4-[(methoxycarbonyl)methyl]-3,4-dihydroisoquinolinones with good tolerance and insensitivity to moisture in one pot under simple and mild conditions.

CO2 hydrogenation into formate and methyl formate using Ru molecular catalysts supported on NNN pincer porous organic polymers

The Ru molecular catalyst immobilized on the porous organic polymer containing the NNN-pincer motif efficiently promoted the hydrogenation of CO₂ into formate derivatives.

Methyl N-phenyl carbamate synthesis from aniline and methyl formate: carbon recycling to chemical products

Methyl N-phenyl carbamate was synthesized from aniline by using methyl formate as a green and efficient carbonylating agent. High yields were obtained at milder reaction conditions compared to the conventional CO/CH3 OH route. Studies on the reaction sequence led to suggest an alternative and more efficient route to the carbamate via formanilide as intermediate.

Hydroformylation of olefins and reductive carbonylation of aryl halides with syngas formed ex situ from dehydrogenative decarbonylation of hexane-1,6-diol

Carbon monoxide and molecular hydrogen are liberated from hexane-1,6-diol in a two-chamber reactor and employed for either a hydroformylation of olefins or a reductive carbonylation of aryl halides.
