Abstract

The Pschorr cyclization of various arylamines with t-butyl thionitrate under nonaqueous conditions gave the, corresponding cyclic products in moderate yields. The same reaction was also found to proceed readily with p-toluenesulfonyl nitrite at room temperature. Treatment of o-aminophenyl allyl ether or sulfide with t-butyl thionitrate resulted in the intramolecular Meerwein arylation to the olefinic bond affording 3-chlorochroman or- ...
