Sandwich und Triple-Decker Complexes of 1,4-Diboracyclohexadienes Starting with 1,4-Dibora-2-cyclohexene DerivativesReactions of 1,4-dibora-2-cyclohexene derivatives 1 with transition-metal complex fragments yield the complexes of 1,4-dibora-2,5-cyclohexadienes 2 by dehydrogenation. The tetra- and tricarbonyl complexes 4a, 5a, b are formed in the reaction of la, b with (CH3CN)3Cr(CO)3 and Fe2(CO)9, respectively: with bis(toluene)iron the sandwich 6b is obtained. The triple- decker complexes 7a and 8a, b are formed from 1 a, b and the dimeric carbonyl (cyclopentadienyl) complexes of nickel and iron, respectively. The bis(methallylnickel) triple-decker 9a is obtained as a mixture of cis/trans isomers, la and [(C2H4)2-RhCl]2 yield the tris(1,4-diboracyclohexadiene)dirhodium triple-decker sandwich 10a by elimination of the ethene ligands and the chlorine bridge.
