An efficient and mild Fe(III)-catalyzed intramolecular Friedel-Crafts alkylation of biaryl methanol derivatives has been developed to achieve the substituted fluorene derivatives. The present reaction provides an excellent alternative to published methods
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.
