Complex [RuCl(η5-C5H5)(PPh3)2], in chloroform at 60 deg C, catalyses the chemoselective insertion of α-diazo carbonyl compounds into N-H and S-H bonds to afford α-keto-amines and α-keto-thioethers.

Reaction of phenols with 2-(isopropylthio)ethyl acetate activated by sulphuryl chloride afforded 2-phenols regioselectively, via sigmatropic rearrangement of phenoxysulphonium ylides.The ortho-alkylated phenols thus obtained have been cyclized with conc. hydrochloric acid in 2-methoxyethanol to 1-benzofurans. 2-Methyl- and 2-phenyl-1-benzofurans have been prepared similarly.
