The reaction of N,N-dimethylacrylamide/triflic anhydride complex with substituted thiophenes led to the corresponding cyclopenta[b]thiophen-1-ones and 1,3-di(2-thiophenyl)propan-1-ones. The application of 2-bromo-N,N-dimethylacrylamide in this reaction allows 2-bromo-substituted five- or seven-membered thiophene-fused cyclic ketones to be obtained.

Here, we report the chemoselectivehydrogenation of α,β-unsaturatedketones catalyzed by a well-defined Mn(I) PCNHCP pincer complex [(PCNHCP)Mn(CO)2H] (1). The reaction is compatible with a wide variety of functional groups that include halides, esters, amides, nitriles, nitro, alkynes, and alkenes, and for most substrates occurs readily at ambient hydrogen pressure (1–2 bar).

在这里,我们报道了由明确的 Mn(I) PC NHC P 钳配合物 [(PC NHC P)Mn(CO) 2 H] 催化的 α,β-不饱和酮的化学选择性氢化 ( 1 )。该反应与多种官能团兼容,包括卤化物、酯、酰胺、腈、硝基、炔烃和烯烃,并且对于大多数底物来说,在环境氢气压力(1-2 bar)下很容易发生。机理研究和氘标记实验揭示了一种非合作机制,本报告将对此进行进一步讨论。
