2,3-Dihydro-1,3,4,5-tetraisopropylimidazol-2-ylidene (1d) is obtained from 1,3,4,5-tetraisopropylimidazolin- 2-thion (2d) and potassium in excellent yield. On comparison with 2,3-dihydro-1,3- diethyl-4,5-dimethylimidazol-2-ylidene (1b) and 2,3-dihydro-1,3-diisopropyl-4,5-dimethylimidazol- 2-ylidene (1c), 2d exhibits a markedly decreased reactivity towards electrophiles which can be explained by differences in the molecular structures in the crystal.
