Potentyally Aromatic Thiophenium Ylides 4. Formation and Cyclization of Methyl and Methoxycarbonyl Substituted 2-(2'-Thienyl)benzoylcarbenes
The catalytic decomposition of methyl- and methoxycarbonyl substituted 2-(2'-diazoacetylphenyl)thiophenes has been studied.The products are accounted for by assuming a primary formation of bicyclic thiophenium ylides.The ylides rearrange to thiopyrans, sp
