资源简介：
A new reaction between chromium(0) and tungsten(0) carbene complexes 1 and alkynyl esters or ketones 2 in the presence of NMO to yield pyran-2-ylidene complexes 3 has been explored. Here, we discuss the scope of the reaction and propose a plausible mechanistic pathway. The method is a new multicomponent approach for the synthesis of pyranylidene carbene complexes.
