Reactions of phosphorus (iv) and orthocarboxylic acid esters with benzal and benzyl halides: pathways and catalysis
摘要
The main pathway of the reaction of benzal and benzyl halides with phosphorus(iv) acid esters followed the dehalophosphonyl/phosphinyl(oxylation) course and led to the corresponding carbonyl-containing compounds or benzyl esters. A new reaction between α-chloro ethers and O-alkyl diethylphosphinates was discovered. The reactions of benzyl halides with esters of phosphorus(iv) and orthocarboxylic acids were catalyzed by anhydrous zinc chloride.
