    Catalytic removal of tert-butyldimethylsilyl (TBS) and tetrahydropyranyl (THP) groups from protected alcohols by NO+BF4 − in methanol

    An effective, catalytic method has been developed to remove TBS and THP groups from protected alcohols. TBS and THP ethers were selectively cleaved using a catalytic amount of NO+BF4 − (5 ...

    Kinetic studies on the single electron transfer reaction between 2, 2, 6, 6-tetramethylpiperidine oxoammonium ions and phenothiazines: the application of Marcus theory

    Electron transfer reactions take place readily between 2, 2, 6, 6-tetramethylpiperidine oxoammonium ions (la,lb) and phenothiazines (2a—2g), giving corresponding nitroxides (3a,3b) and phenothiazine radical catio...
