Heteroleptic Tertiary Arsines, Me2AsR: Synthesis and an Nmr Study

摘要

Tertiary arsines of the type Me2AsR R = Et, Prn, Pri, Bun, Bui, But, allyl, Me3SiCH2, Ph, Bzl, mesityf, and p-totyl have been synthesized in excellent yields by alkylating Me2AsNMe2with Grignard reagents. The utility of aluminum alkyls as alternative alkylating agents for certain arsines has also been demonstrated. All compounds have been characterized using IR, MS, and NMR spectroscopy. An NMR spectral analysis (1H,13C, and29Si) is given and these results are compared with those for the homoleptic arsines, R3AS.
