α-(N-Sulfonyl)amino amides from a carbamoylsilane and N-sulfonylimine

Generation of (amino)(boryloxy)carbenes from carbamoylboranes and their coupling reaction with aldehydes

Carbamoylboranes were found to react with various aldehydes under heating conditions to give α-hydroxycarboxamides in good yields. A DFT study supports the mechanism, which involves thermally generated (amino)(boryloxy)carbene intermediates. To our knowledge, this is the first report on the generation of (amino)(boryloxy)carbene intermediates from carbamoylboranes and its application to carbon-carbon bond-forming reactions.

Nickel-catalyzed aminocarbonylation of aryl halides using carbamoylsilane as an amide source

The nickel-catalyzed aminocarbonylation reaction of aryl halides using carbamoylsilanes as an amide source in toluene is developed leading to the formation of some tertiary or secondary aryl amides in good yields.
