摘要

The transition-metal-catalysed decomposition of diazo compounds is a well-established and powerful strategy to access metal carbenoids, which may then be used to generate reactive intermediates. A powerful example is the Doyle–Kirmse reaction, which generates new C–C and C–S bonds (Scheme 1), most notably under Rh(II) and Cu(I) catalysis. 1 In this process, an allyl sulfide 3 reacts with carbenoid 2 to give a sulfur ylide intermediate 4 that is ...
