摘要：

The approximate rate constants for 5-exo and 6-exo cyclizations of alkyl radicals onto imines have been kinetically determined to be 6.0x10(6) s(-1) and 6.7x10(5) s(-1) at 80 degrees C, respectively. Alkyl radical additions to imines were essentially irreversible and considerably slower than alkyl radical additions to hydrazones. Copyright (C) 1996 Elsevier Science Ltd
