Iron-catalyzed cross coupling of P-H/C-O bonds: efficient synthesis of α-alkoxyphosphorus compounds

Tin(ii)-catalyzed dehydrative cross-coupling of 2H-chromene hemiacetals with ketones

Without the derivatization of 2H-chromene hemiacetals to 2H-chromene acetals, the direct C–OH/C–H coupling reaction has been accomplished with water as the only by-product.

HClO4 catalysed aldol-type reaction of fluorinated silyl enol ethers with acetals or ketals toward fluoroalkyl ethers

A highly efficient metal-free catalytic aldol-type reaction of fluorinated enol silyl ethers and acetals/ketals toward functionalized fluoroalkyl ethers is developed by using less than 1.0 mol% HClO₄ (70 wt%, aq.).

Construction of β-Trifluoromethyl Enol Ether via Base-Promoted C-O Coupling and Rearrangement of Hydrogen Atom

A novel, high-efficiency and high-selectivity construction of β-trifluoromethyl enol ether via base-induced/promoted C-O coupling of trifluoromethylated vinyl chloride and phenols is presented with a broad substrate scope. The reaction mechanism, especially the significantly high selectivity, was excavated and understood via DFT calculation and is well supported by the experimental observation.
