A scandium-triflate-catalyzed arylative desulfonation of diarylmethyl phenyl sulfones with arenes and heteroarenes was established. A variety of both sulfone and arene substrates were reacted to afford symmetric and nonsymmetric triarylmethanes in good yields. Further transformations of the resulting triarylmethanes and application to the concise synthesis of a bactericidal agent analogue were also demonstrated.

Organocatalytic Friedel–Crafts Benzylation of Heteroaromatic and Aromatic Compounds via an SN1 Pathway
The Friedel-Crafts-type benzylation of various -excessive heteroaromatic and aromatic compounds with trityl or benzhydryl halides was efficiently promoted by a thiourea catalyst. This is a novel example of thiourea catalysis of aromatic alkylation by way of an S(N)1 pathway.

With our compliments: The 1,3‐dicarbonyl unit has been shown to be a new and useful leaving group for iron‐catalyzed bond cleavage (see scheme). This new strategy can complement the traditional Friedel–Crafts reaction and was applied in the synthesis of indene derivatives.
