The Reaction of Dimethylalkynylaluminum Reagents with Trimethylsilyldiazomethane: Original Reactivity Leading to New α-Silylated Alkynyl Hydrazones
摘要:
Trimethylsilyl (TMS) diazomethane does not react as a homologating reagent but as a C-electrophilic species with dimethylalkynylaluminum reagents. This unprecedented reactivity enables a simple access to unusual a-silylated alkynyl hydrazones.
