AbstractSynthesis and properties of tris(phosphane)(ethene)nickel(0) complexes (dmpe)(PR3)Ni(C2H4) (R = CH3(4), c-C6H11(5), and C6H5 (6)) are reported. In solution. 4-6 are thermolabile and undergo ligand exchange reactions affording tetrakis(phosphane)nickel(0 ) and bis(phosphane)- (ethene)nickel(0) complexes. 1H, 13C, and 31P NMR data of 4-6 confirm the tetrahedral geometry around nickel. For 6 , the crystal and molecular structure has been determined by X-ray crystallography.

Novel (arene)titanium(II) haloaluminate complexes (η6-arene)Ti[(μ-X)2AlX2]2 (X = Cl, Br) were obtained from (η6-benzene)Ti[(μ-X)2AlX2]2 (X = Cl, Br) complexes by ligand exchange reactions with bis(pentamethylphenyl)methane and dimesitylmethane. The [η6-1,2,3,4,5- pentamethyl-6-(2,3,4,5,6-pentamethylbenzyl)benzene]Ti[(μ-X)2AlX2]2 (X = Cl, Br) and [η6-1,3,5- trimethyl-2-(2,4,6-trimethylbenzyl)benzene]Ti[(μ-Br)2AlBr2]2 complexes containing titanium coordinated to only one of the two phenyl rings were obtained and their crystal structures were determined. (η6-Benzene)Ti[(μ-Cl)2AlCl2]2 and dimesitylmethane afforded the (η6-mesi- tylene)Ti[(μ-Cl)2AlCl2]2 complex which is isotypic with the known bromo analogue. This product shows that Friedel-Crafts scission of aryl-alkyl bonds occurs in such systems even under mild conditions.
