Abstract

Transition-metal carbenoids are known to be valuable key intermediates for various synthetic transformations, such as cycloaddition reactions, olefin metathesis, reactions via reactive ylides, and insertion reactions into σ bonds.(1) To avoid the use of hazardous diazo compounds as metal carbenoid precursors, facile methods for generation of transition-metal carbenoids from alkynes have been developed.(2-8) In most cases, intramolecular attack of a nucleophile ...
