Concurrent base and silver() catalysis pulsed by fuel acid

摘要

Treatment of a crown-ether receptor and a silver(i)-loaded cyclam derivative (NetState-I) with a fuel acid reversibly afforded the protonated cyclam and the silver(i)-loaded crown ether (NetState-II). While NetState-I was catalytically OFF, a base-catalysed Michael addition and a silver(i)-catalysed oxime cyclisation reaction was pulsed under dissipative conditions in NetState-II.
