the formyl group). In these latter cases the pinacol coupling was diastereorandom. A 3-formyl-4-(2-formylaryl)-1-sulfinyl-(1Z,3E)-butadiene irontricarbonylcomplex also underwent diastereoselective pinacol coupling (22:1 dr). 3-(3-Formylindolyl)-1-sulfinyl-(1Z,3E)-pentadien-5-al irontricarbonylcomplexes were also prepared, though pinacol coupling of these substrates proceeded in, at best, modest yield
