Five- and six-membered cobaltocycles with C,P-chelating ligands through regiospecific cyclometalation of mono(2-substituted) triphenylphosphane

Cyclometalation in the aliphatic ring occurs in the reaction between [CoCH3(PMe3)4] and 5-(diphenylphosphanyl)-1,2,3,4-tetrahydronaphthalene to give [{8-(diphenylphosphanyl)-1,2,3,4-tetrahydronaphthyl-(C1,P)} tris(trimethylphosphane)cobalt] (1), containing a five-membered metallacycle as shown in the molecular structure. While 1-(diphenylphosphanyl)naphthalene reacts accordingly, affording [{8-(diphenylphosphanyl)naphthyl-(C1,P)}tris(trimethylphos phane)cobalt] (2), 2-(diphenylphosphanyl)biphenyl yields ortho-metalated [{2-(diphenylphosphanyl)-3-phenylphenyl-(C1,P)}tris (trimethylphosphane)cobalt] (3), containing a four-membered metallacycle. 1-(Diphenylphosphanyl)-8-methylnaphthalene is metalated in the aliphatic substituent to form [{[8-(diphenylphosphanyl)naphth-1-yl]methyl-(C,P)}tris (trimethylphosphane)cobalt] (4). The molecular structure shows a trigonal-bipyramidal configuration of the cobalt atom accommodating a six-membered metallacycle. 2-(Diphenylphosphanyl)styrene replaces two trimethylphosphane ligands to give [{2-(diphenylphosphanyl)styrene-(C,C-η2,P)/methyl-bis (trimethylphosphane)cobalt] (5), avoiding metalation. Replacement of equatorial trimethylphosphane in compounds 1-3 by ethene gives π-ethene complexes 6-8. In the molecular structure of 7 the C-C vector of the π-ethene ligand is arranged in the equatorial plane of a trigonal bipyramid. Under 1 bar of CO, compound 2 forms a monocarbonyl complex 9, in which an equatorial carbonyl ligand is found in the molecular structure. Iodomethane transforms 2 into pentacoordinate [{2-(diphenylphosphanyl)naphthyl-(C1,P)/iodobis- (trimethylphosphane)cobalt] (10) with retention of the metallacycle. Wiley-VCH Verlag GmbH & Co.
