furnishes N‐arylhydroxamic acids in high yields. Aromatic aldehydes and benzoins are converted into enamine‐carbanion‐like intermediates prior to their reaction with nitroso compounds. The kinetic resolution of rac‐2‐hydroxy‐1,2‐diphenylethanones furnished (S)‐benzoins and arylhydroxamic acids with high enantioselectivities and conversions.

Six new triorganotin(IV) complexes with six different RN-2-X-benzohydroxamic acid ligands having general formula R'C(O)N(RN)OH (R' = alkyl/aryl; RN = alkyl/aryl or H), (X = -I, -NO2, -OCH3, -Br and R = -CH3, -C6H5 and -C6H4-CH3), were prepared by condensation method with the respective organotin(IV) chlorides using a stoichiometric ratio of 1:1. The bonding and coordination behaviour of these complexes were investigated on the basis of FT-IR, multinuclear H-1, C-13 and Sn-119 NMR spectroscopies. Complexes (1) and (3) crystallize in the orthorhombic P2(1)2(1)2(1) space group and complex (2) crystallizes in the triclinic P-1 space group whereas complex (4) crystallizes in the monoclinic P2(1)/c space group. The tested triphenyltin(IV) complexes showed significant cytotoxicities, higher than doxorubicin toward K-562, Jurkat, HepG2 and L929 cells. (C) 2014 Elsevier B.V. All rights reserved.
