2'-Dithiobis(benzothiazole) is used as a fungicide, insecticide, sensitizer and anti-scorching agent in vulcanization of rubber.5 2-Mercaptobenzimidazole (MBI) is an important chemical for many industrial applications, such as an inhibitor for copper plating, antioxidant for plating rubber compounds, adsorbent for heavy metal, antiseptic and medical substances.6-8 MBI is used as a non-staining secondary antioxidant
(hetero)aromatic substituents, were also prepared and evaluated. By contrast, the insecticidalactivities of compounds containing the short thioether bridge, 1,2-bis((hetero)aromatic thio) ethane, are higher than that containing the long thioether bridge, 1,3-bis((hetero)aromatic thio) propane. The results of moleculardocking and pharmacophore analyses indicated A299, T303, and L306 of a subunit were essential

The cross-electrophile dialkylation of alkenes enables the formation of two C(sp3)–C(sp3) bonds from readily available starting materials in a single transformation, thereby providing a modular and expedient approach to building structural complexity in organic synthesis. Herein, we exploit the disparate electronic and steric properties of alkyl halides with varying degrees of substitution to accomplish

A class of (E) and (Z)-3-styrylpiperidine derivatives was prepared as racemates and evaluated for affinity at sigma binding sites labeled with [H-3]-(+)-SKF-10,047. Some of these compounds exhibited high affinity and selectivity for sigma versus D-1 and D-2 binding sites. (C) 1997 Elsevier Science Ltd.
