Abstract
The reactions of the new bis(5-formyl-2-heteroaryl)dimethylsilanes 5, 6, and bis(3-formylphenyl)dimethylsilane 13, obtained from the corresp onding acetals, with phosphono-dihydrazides PhP(X)[(N(CH3)NH2)]2 14 (X = S) or 15 (X = 0) led quantitatively to the silicon- and phosphorus- containing macrocycles 16-20 arising from selective [2 + 2] cycloconde nsation reactions.
