Synthesis, structure, and reactivity of the first diazagermocines
摘要:
New 1,3,2-diazagermines 2, formed by reaction of 4-amino-1-azabutadienes 1 and diethyl- or diphenylgermanium dichloride, react with dimethyl acetylenedicarboxylate to yield novel 1,5,2-diazagermocines 3 in quantitative yield; the crystal structure of 3a has been determined. The behavior of 3 toward hydrolysis and heating is also reported.
