Synthesis of a dimeric phosphine-stabilized phosphidogermanium(i)–amidogermanium(ii) derivative†
Abstract
The synthesis of a dimeric phosphine-stabilized phosphidogermanium(I)–amidogermanium(II) derivative is described. The reaction of amidinato phosphinoamidosilylene [L{(Ar)(Ph2P)N}Si:] (1, L = PhC(NtBu)2, Ar = 2,6-iPr2C6H3) with GeCl2·dioxane afforded a phosphine-stabilized phosphidogermanium(I) dimer moiety in a mixed-valent germanium(I,II) compound [:Ge(Cl){N(Ar)PPh2}(Ph2P)Ge:]2 (3). The mechanism for the formation of 3 is also studied and reported.
