A photochemical desilylation reaction with nearly quantilative yield and excellent selectivity between silyl alkyl ether and silyl enol ether is reported.
The reactions of N-alkylphenothiasine (1) radical cations with 2, 4-dinitrophenylhydrazin. (2) were studied. Product analysis showed that the oxidative coupling product 3-(2', 4'-dinitrophenylazo)-N-alkylpheno...The reactions of N-alkylphenothiasine (1) radical cations with 2, 4-dinitrophenylhydrazin. (2) were studied. Product analysis showed that the oxidative coupling product 3-(2', 4'-dinitrophenylazo)-N-alkylphenothiazine (3) was formed, which was characterized by AS, IR, NMR and X-ray diffraction.展开更多
