α-Chlorination with carbon tetrachloride and α-1H/2H exchange with [2H]chloroform of amidines
Abstract
The bicyclic amidines (1)–(4) have been found to be α-chlorinated with carbon tetrachloride at room temperature in darkness under nitrogen, (1) and (3) also undergo 1H–2H exchange in the α-position with [2H]-chloroform.
