Herein we report the 3,5-bistrifluoromethylphenyl urea-catalyzed functionalization of unactivated C-H bonds. In this system, the urea catalyst mediates the formation of high-energy vinyl carbocations that undergo facile C-H insertion and Friedel-Crafts re

Hydroacylation of 1-alkene with a heteroaromatic aldehyde such as pyridinecarboxaldehyde, thiophenecarboxaldehyde and furfural derivatives under cocatalyst of Wilkinson's complex and 2-amino-3-picoline gave poor yield of hydroacylated product. The addition of a catalytic amount of bis(cyclopentadienyl)zirconium dichloride or bis(cyclopentadienyl)titanium dichloride as an additive dramatically increased the yield of the hydroacylated ketone product.
STERIC EFFECTS IN THE REACTION OF DI(BROMOMAGNESIO)ALKANES WITH CARBOXYLIC ESTERS

Largely different product distributions were observed on the action of various carboxylic esters with 1,4-di(bromomagnesio)butane and its homologue 1,5-di(bromomagnesio)pentane.The much larger yields of reduction product with the latter are the evidence for the structural geometric requirements for the annelation step.
