Reaction of lithium trimethylsilyldiazomethanide with ketenimines bearing electron-withdrawing groups

Ketenimines bearing electron-withdrawing groups (X in 1) at the C2-position react with lithium trimethylsilyldiazomethanide [diazo(lithio)trimethylsilylmethane] to give 4-amino-3-trimethylsilylpyrazoles 4 or 5 mainly; in some cases 4-trimethylsilyl-1,2,3-triazole derivatives 3 were formed as the major products.
