4-(C5H10N)2-C4Fe(CO)3 in accord with head-to-tail dimerization of the acetylene. Reactions of (CH3)3SiCCNR2 with Fe2(CO)9 in diethyl ether at room temperature give orange-red (CH3)3SiC2NR2Fe2(CO)6 suggested by their NMR spectra to have the nitrogen atom as well as the two acetylenic carbon atoms involved in the bonding to the diiron unit. Reactions of (CH3)3SiCCNR2 with Co2(CO)8 in diethyl ether at ambient temperature

Metallated ynamines 5a-f and ynehydrazines 5g,h were prepared in a very short reaction sequence by consecutive treatment of trichloroethylene (1) with the lithium salt of secondary amines or of trimethylhydrazine, 2 equivalents of butyllithium and chlorotriorganosilanes or -stannanes.
