Potentially Aromatic Thiophenium Ylides. V. Reactions of Ethoxycarbonyl- (and Methoxycarbonyl)-2-(2-thienyl)phenylcarbene

In an attempt to make thiophenium ylides in which the ylide bond is part of a five-membered ring annulated to the α-side of the thiophene moiety, two alkoxycarbonyl substituted 2-(2-thienyl)phenylcarbenes have been made, with and without chlorine substituents in the remaining thiophene positions.With rhodium acetate as a catalyst the carbene without chlorines cyclized to the 3-position of the thiophene to give a fluorene analogue, whereas no cyclization was detected when the 3-position was blocked.

Potentially Aromatic Thiophenium Ylides 3. Cyclization of 2-(2'-Thienyl)benzoylcarbene

Catalytic decomposition of 2(2'-diazoacetylphenyl)thiophene gives the 4,10b-dihydro-indacyclopropathiophen-6-one (5) and the naphthothiophen-5-ol (6).It is shown that 5 rearranges to 6 under acid catalysis.The mechanisms for the r
