Photoredox catalytic cyclization of aryl enones in the presence visible light, promoted either by metals or organic dyes, represent a valuable strategy for synthesis cycloalkanes. The development stereoselective version such transformation, metal-free catalyst Eosin Y was studied, with aim to realize an efficient protocol in-flow enantiomerically enriched functionalized cyclopentane rings, taki...

A fluorosulfoxonium cation and triflic acid were shown to promote ( n + 2) annulations of donor–acceptor cyclopropanes or -butanes with 1,2-dipoles, different activity selectivity but a presumed similar role as (hidden) Brønsted acids.

The catalytic conversion of palm oil was carried out over four zeolite catalysts—Y, ZSM-5, Y-ZSM-5 hybrid, and Y/ZSM-5 composite—to produce jet biofuel with high amount alkanes low aromatic hydrocarbons. hybrid catalyst synthesized using crystalline Y as the seed for growth ZSM-5. Synthesized catalysts were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, field-emiss...
