✦ Synopsis

Bromine-lithium exchange in l,l-dibromo-3-(trimethylsilyl-silylating agents. Diastereoselectivity in the generation and oxy)alkanes 4 and 6 affords the carbenoids 8 and 14, which trapping of the carbenoids ranged between 70 -90% for 8 and have been added to ketones, aldehydes, arylboronates, and >90% for 14.
