The first stable 3,1-germaphosphaallene Tip(t-Bu)Ge=C=PAr

The first stable heteroallenic derivative with two heavy doubly-bonded Group 14 and 15 elements, the germaphosphaallene Tip(t-Bu)Ge=C=PAr 1 (Tip = 2,4,6-triisopropylphenyl, Ar = 2,4,6-tri-tert-butylphenyl), has been prepared in a nearly quantitative yield by dechlorofluorination of Tip(t-Bu)Ge(F)-C(C1)=PAr (obtained from ArP=CC12 and successive reaction with n-butyllithium and Tip(t-Bu)GeF2) with tert-butyllithium. 1 gives [2 + 2] cycloadducts by the Ge=C double bond with benzaldehyde, benzophenone and fluorenone to afford the corresponding germaoxetanes 11 - 13. 13 has been structurally characterized showing a long Ge-O bond (1.821(2) ?) and a slightly folded four-membered ring GeOCC (18.8° along C(1)Ge axis).
