1,1-Dialkyl(aryl)-1-silacyclohexa-2,4-dienes react with tris(acetonitrile)-molybdenum tricarbonyl and -tungsten tricarbonyl to give the corresponding dicarbonyl complexes with two silacyclohexadiene ligands.Complexes with functional groups at the silicon atom (chlorine, alkoxy) can be prepared analogously. 1,6-Dichloro-1-methyl-4-cyclohexyl-1-silacyclohexa-2,4-diene reacts with (CH3CN3)3Mo(CO)3 similarly to the dimerisation of the ?-allyl complexes, by dehalogenation and dimerisation at C(6). 1H-1-Methyl-4-cyclohexyl-1-silacyclohexa-2,4-diene dimerizes with (CH3CN)3Mo(CO)3, probably with the isomeric 1-silacyclohexa-1,3-diene as intermediate, to give a 1,3-disilacyclobutane derivative.
