Abstract
The preparation of tetraalkyl 1,3-phenylene-di(methylamino)-di-ferrocenylmethyl-phosph onates (4a–c) and tetraalkyl 1,3-cyclohexylene-di(methylamino)-di-ferrocenylmethylphosph onates (5a–c) by the addition of dialkyl phosphites to N,N-diferrocenylidene-1,3-phenylenedimethylamine 1 and N,N-diferrocenylidene-1,3-cyclohexylenedimethylamine 2 is described. The diastereoselectivity, which was observed in both cases, is consistent with that observed in other cases.
