The synthesis of a number of benzylphenylsulphides, substituted in the α-position of the benzyl moiety, is described and their toxicities to the eggs and young mites of the glasshouseredspider (Tetranychus telarius L.) are tabulated.

A highly-efficient and practical method for S-alkylation of arylthioureas was reported. Using tetraalkylammonium salts as alkylation reagents, a series of 68 S-substituted aryl-isothioureas were obtained in good to excellent yields under transition-metal-free conditions. The protocol features simple performance, broad functional group tolerance, good to excellent yields, and easily available starting
A series of Thiazole Orange (TO) derivatives were synthesized and modified by introducing different substitutional groups on benzothiazole and 4-methylquinoline All the TO derivatives were confirmed by (HNMR)-H-1 and MS. TO derivative bearing NH2- was modified by folic acid and used to label breast cancer cells. The phenomenon of fluorescence enhancement was shown by the fluorescence spectrums of TO derivatives and micrographs of the labeled breast cancer cells. It offered a new try in the aspect of labeling cells by the embedded dyes. (C) 2008 Elsevier Ltd. All rights reserved.
