Bicyclic cyclopentadienes 5b,c and 12b,c in which an N,S‐chelating group is attached to the cyclopentadiene ring were obtained in good chemical yields by reaction of [1‐alkynyl‐2‐(1‐cycloalkenyl)]carbene complexes 1a−d (M = W, Cr) with pyridine‐2(1H)‐thione (2a) and N‐phenylthioacetamide (2b), respe...
