Herein we report a simple and efficient methodology for the synthesis of thioacetates using benzyltriethylammonium tetrathiomolybdate and acetic anhydride as the key reagents, starting from alkyl halides in a multistep, tandem reaction process. Its application in the synthesis of orthogonally protected cysteine and anomeric β-thioglycosides has also been demonstrated.
An electrochemical sensor incorporates a ferrocenophane which is a compound with at least one bridging group covalently attached to and connecting the two cyclopentadiene rings associated with the same iron atom. This bridging group maybe tetramethylene. As compared to an equivalent sensor with ferrocene, the tolerance of elevated temperature is improved and so is the working life at ambient temperature.
