From: Photocatalytic deoxygenative Z-selective olefination of aliphatic alcohols
A Screening of phenothiazine derivatives for the photocatalytic activation of neutral benzoates. Reaction conditions: 14 (0.1 mmol), γ-terpinene (0.2 mmol), photocatalyst (10 mol%) in DMSO (0.1 M) at rt for 16 h, 390 nm LED. B Optimization and control experiments for the deoxygenative Z-selective olefination of alcohols. Reaction conditions: 14 (0.1 mmol), styryl boron species (0.3 mmol), catechol (0.1 mmol), photocatalyst 19 (10 mol%) in DMSO (0.33 M) at rt for 16 h, 390 nm LED. a 1H NMR yields using methyl 3,5-dinitrobenzoate as internal standard. b Z:E ratio determined by 1H NMR. DMSO: dimethyl sulfoxide.
