摘要

Abstract While optimized procedures for selective propargylic–versus allenic–attack (in particular by alkynylsilanes) have proven to be compatible with many substitution patterns at the propargylic center, the case of diarylpropargyl electrophiles has remained problematic. The intrinsic reactivity of 1, 1-diphenylpropargylic alcohols [R–C≡ C–C (Ph 2) OH (R= TMS, H, Me)] in the presence of various acids (and in the absence of additional nucleophile) ...
