Abstract
The synthesis of the inter- and intra-molecular donor-stabilized 1-metalla-2-sila-1,3-dienes Cl(H2CCH)SiMLn·OP(NMe2)3[MLn= Fe(CO)4 3a, Cr(CO)5 3b], Ph(PhHCCH)SiFe(CO)4·OP(NMe2)3 3c and (C6H4CH2NMe2-2)(H2CCH)Si MLn[MLn= Fe(CO)4 6a, Cr(CO)5 6b] is described; the X-ray structures of compounds 3c and 6b are reported.
