New insights into the selective and systematic preparation of arylgermanium hydrides

摘要

A series of novel arylgermanium hydrides ArnGeH4-n (n = 1-3) and diaryl(chloro)germanium hydrides Ar2Ge(Cl)H were synthesized and characterized. Systematic preparation and purification were achieved via the lithium chloride-triflic acid and the optimized Grignard route. Arylgermanium hydrides ArnGeH4-n (Ar = 2,5-Me2C6H3, n = 1-3) were characterized by H-1 and Ge-73 NMR spectroscopy and single crystal X-ray diffractometry.
