When solid-state rhenium sulfide clusters with an octahedral metal framework are treated in a hydrogen stream above 300°C, a catalytic activity for condensation of butylamine to yield N- butylidenebutylamine develops. Primary amines such as ethylamine, pentylamine, and hexylamine are also converted ...

Direct and highly selective conversion of benzylic, allylic and propargylic TMS, TBDMS and THP ethers into their corresponding iodides with the SiO2–Cl/NaI system is described. Reactions were conducted in CH3CN at room temperature. Aliphatic silyl and tetrahydropyranyl ethers remained almost intact ...
