We disclose an unprecedented transition-metal-free carbonylative cross coupling of arylhalides with potassium aryl trifluoroborates even at atmospheric pressure of carbon monoxide. This protocol is efficient, operationally simple, and shows...
AbstractLewis‐base‐catalyzed asymmetric hydrosilylation of substituted benzophenone N‐aryl imines was investigated. Among various chiral Lewis‐base catalysts, a catalyst derived from L‐Serine was found to be the most favorable one which promote the reaction to afford a series of (diarylmethyl)amines with high yields (up to 97 %) in moderate to good enantioselectivities (up to 97 % ee). The absolute configuration of the product was determined by the X‐ray crystallographic analysis.magnified image
