An atom economic and catalytic substitution reaction of π-activated alcohols by a multimetallic IreSn3 complex has been demonstrated. The multimetallic IreSn3 complex can be easily synthesized from the reaction between [Cp*IrCl2]2 and SnCl2. In presence of as little as 1 mol % of the catalyst three different types of π-activated alcohols, namely benzyl, allyl, and propargyl alcohols, have been successfully transformed into alkylated products using carbon (arenes, heteroarenes, allyltrimethylsilane, and 1,3-dicarbonyls), nitrogen (sulfonamides), oxygen (alcohols), and sulfur (thiols) nucleophiles in very high yields. An electrophilic mechanism is proposed from the Hammett correlation study.

Grignard reagents react with thiobenzophenone to give mainly the compound resulting from addition of the' organic radical to the sulfur atom. Addition to carbon, double addition both to sulfur and to carbon, and formation of tetraphenylthiiranne are also observed. The stable alkylthiodiphenylmethyl radical has been detected in the reaction medium. A mechanism is proposed to account for the various reactions.
