efficient catalyst for the cyanosilylation of various ketones and aldehydes. The reactions were complete within 30 minutes at room temperature in the presence of only one mol% gold(III) chloride, yielding the corresponding cyanohydrin trimethylsilyl ethers in very good yields. The isolated yields for the reactions of ketones were up to 98%, and the reactions of aldehydes gave 100% conversion, as monitored

2-cyanofunctionalization of unactivatedalkenes involving remote cyano migration triggered by addition of diverse carbon- and heteroatom-centered radicals to alkenes has been developed. This powerful strategy provides a diverse platform for the collection of a variety of synthetically important β-functionalized alkyl nitriles bearing densely functionalized carbonyl, cyano, and other various functional groups within
An oximinotrifluoromethylation of unactivated alkenes was developed via trifluoromethyl radical-induced intramolecular remote oximino migration under mild reaction conditions.

We report the synthesis and structuralcharacterization of a series of novel zinc (II) and cadmium (II) complexes with the chemical composition, [κ2-N,E-C5H4NCH2N(H)PPh2(E)}MX2] (M = Zn; E = Se, X = Cl (1a), Br (1b), I (1c); E = S, X = Cl (2a), Br (2b), I (2c) and M = Cd; E = Se, X = Cl (3a), I (3b); E = S, X = Cl (4a), I (4b)). These complexes are easy to prepare and air-stable. The single-crystal
