Remazol-Catalyzed Hydroperoxyarylation of Styrenes

Chen, Ying-Ho,Lee, Ming,Lin, Yi-Zhen,Leow, Dasheng

, p. 1618 - 1621 (2015)

A mild photocatalytic hydroperoxyarylation of styrenes has been developed, in which a novel photocatalyst, remazol brilliant blue R (RBBR), is employed at low catalytic loading (1 mol%). The operationally easy procedure uses air as the dioxygen source. Simple mono-substituted styrenes react with aryl hydrazines in moderate-to-good yields. RBBR is proposed to act as a photosensitizer for the generation of singlet oxygen.
