TL;DR: A review of the development of this new reaction type and critically compares the reaction and catalyst concepts disclosed in the literature can be found in this paper, where the functionalization of a C-H bond and the incorporation of CO2 into an organic molecule without need for strong bases or aggressive organometallic reagents are discussed.

TL;DR: In this paper, a substantial advance was recently made in the development of direct C H carboxylations mediated by coinage metals, and several catalytic processes for CO2 fixation have emerged that allow for example, the carboxylic cyclization of propargylic amines and alcohols, the reductive carboxymylation of alkynes and alkenes, and the hydrosilylation of CO2 under mild conditions.

TL;DR: A comprehensive mechanistic study of the ruthenium-catalyzed hydroamidation of terminal alkynes, which includes deuterium-labeling, in situ IR,In situ NMR, and in situ ESI-MS experiments complemented by computational studies, supports the involvement of rutenium-hydride and ruthensium-vinylidene species as the key intermediates.

TL;DR: In this article, a rational catalyst development based on mechanistic and spectroscopic investigations led to the discovery of a new protocol for catalytic hydroamidation reactions that draws on easily available ruthenium trichloride trihydrate (RuCl 3 ·3H 2 O) as the catalyst precursor instead of the previously employed, expensive bis(2-methylallyl)(1,5-cyclooctadiene)ruthenius(II).
