Two-phase reactions in the chemistry of carbanions and halocarbenes. A useful tool in organic synthesis
Abstract
Reactions of organic anions—L
Abstract A useful new method of preparation of phenyl(trihalomethyl)mercury compounds has been elaborated. It consists of the reaction of haloforms (chloroform, bromoform, and mixed trihalomethanes) with phenylmercury chloride in the presence of aqueous NaOH/KF solution with a quaternary ammonium compound, triethylbenzylammonium chloride, as a catalyst.
Catalytic removal of tert-butyldimethylsilyl (TBS) ether by PVP-I
Abstract A mild, efficient and rapid protocol the deprotection of alcoholic TBDMS ethers using PVP-1 as catalyst in methanol, the procedure of deprotection of various TBDMS ethers were found to be very convenient, easy work-up, high yielding.
