Aryne chemistry. Part XXXIII. Reactions of tetrahalogenobenzynes with methoxyarenes and the photolysis and thermolysis of some of the products
Abstract
The reactions of tetrahalogenobenzynes with methoxyarenes afford good yields of both 1,4-dihydro-1-methoxy-1,4-ethenonaphthalene derivatives and, in certain cases, 3,4-dihydro-1,4-ethenonaphthalen-2(1H)-ones. Thermolysis or photolysis of these compounds leads to naphthalene derivatives in high yield.
