Compared to dichlorocarbene from other sources the highly reactive dichloro carbene reagent of Makosza and Wawrzyniewicz gives better yields of bis- und tris-adducts even with compounds lacking activation. Compounds 4, 10, and 11 have been prepared for the first time; Compounds 10 and 11 show unusual long-range couplings between methyl protons 5 bonds apart.
