Reactions of Trimethylaluminum with Secondary Arsines: Synthesis and Characterization of Phenyl(trimethylsilylmethyl)arsine, Ph(Me3SiCH2)AsH, and the X-Ray Crystal Structures of the Trimers, Me2AlAsPh2!3.(C7H8)2 and Me2AlAs(CH2SiMe3)Ph3.

Abstract

The reactions of trimethylaluminum with diphenylarsine, Ph2AsH, and phenyl(trimethylsilylmethyl)arsine, Ph(Me3SiCH2)AsH, in 1:1 mole ratios afford the trimeric compounds Me2AlAsPh23.(C7H8)2 (1) and Me2AlAs(CH2SiMe3)Ph3 (2), respectively. Compounds 1 and 2 are the first Al-As six-membered ring compounds to be structurally characterized by single-crystal X-ray crystallography, as well as 1H and 13C solution NMR spectroscopy. X-ray crystallographic analysis revealed that trimer 1 is a toluate which crystallizes in the monoclinic space group P 2 sub 1/n, with a = 14.549(6) A, b =22.838(7) A, c = 16.891(4) A, and beta = 105.12(5) deg for Z =4.
