摘要：

Reaction of amino(imino)phosphanes 1a-c with gallium trichloride results in the formation of 1,3-diaza-2 lambda(2)-phosphonia-4 lambda(4)-gallatacyclobutanes 3a, b with elimination of chlorotrimethylsilane (1a) or tert-butyl chloride (1b, c). The interimediately formed amino (imino)phosphane/Lewis acid adducts R(Me(3)Si)NPN(GaCl3)R' (2, R,R' = tBu, Me(3)Si) can be isolated in the case of compound 2a (R = R'= SiMe(3)). A diazaphosphasilacyclobutane-gallium trichloride adduct 4 is formed in a side reaction by isomerization of 2a. Reaction of compound 3b with Ni(CO)(4) gives the corresponding transition metal complex 5. The NMR data and X-ray structures of compounds 2a, 4, and 5 are reported.
