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

Die vorliegende Erfindung betrifft neue Schädlingsbekämpfungsmittel enthaltend eine Wirkstoffkombination aus substituierten Benzazolen der Formel (I)
wobei die Definition der Reste aus der Beschreibung ersichtlich ist und anderen bekannten pestiziden, insbesondere insektiziden und akariziden Wirkstoffen.
Two-part cyanoacrylate compositions, methods for making same, and uses therefor are described. The compositions can be used to bond a variety of substrates including plastics and metals. The compositions remain effective after thermal ageing and humid ageing.
There is provided a cyanoacrylate composition comprising:
a cyanoacrylate; and
a 2-substituted benzothiazole or a derivative thereof
wherein the 2-substituent is an alkyl, an alkene, an alkylbenzyl, an alkylamino, an alkoxy, an alkylhydroxy, an ether, a sulfenamide, a thioalkyl or a thioalkoxy group, with the proviso that an amide portion of the sulfenamide does not have a tert butylamino or a morpholine group.
