摘要：

Alpha,omega-tertiary diamines react under high pressure with alpha,omega-di-iodo compounds to give the cyclic bis-quaternary salts in almost quantitative yields. It is also shown that the same reaction can be carried out under atmospheric-pressure conditions with slightly lower yields. Subsequent demethylation of the bis-quaternary salts with triphenylphosphine affords N,N'-dimethyl diazacoronands in high yield.
