Electrophilic Reactions of Activated Alkenes and Alkynes with Element Halides. III. Reaction of Activated Alkenes with Phosphorus Trihalides

Electrophilic substitution of the vinyl hydrogen atom in alkenyl alkyl ethers, 2-bromoethenyl alkyl ethers, and ketene acetals readily occurs under the action of phosphorus trihalides in the presence of an organic base to yield 70-98% of 2-alkoxy-, 2-alkoxy-1-bromo-, and 2,2-dialkoxyalkenylphosphonous dichlorides and dibromides. The reaction is regio- and stereospecific. A mechanism involving intermediate formation of a cyclic phosphiranium ion is proposed.

AN IMPROVED METHOD FOR THE EFFICIENT CONVERSION OF UNSATURATED ALCOHOLS, ETHERS AND ESTERS TO THEIR CORRESPONDING ALDEHYDES, KETONES, ENOL ETHERS AND ENOL ESTERS

Catalytic conversion of unsaturated alcohols to their corresponding aldehydes and ketones with nonacarbonyl diiron in benzene at 40-50 deg C are performed efficiently in high yields.The efficient preparation of some enol ethers and also preparation of a few esters from their corresponding unsaturated ethers and esters are also performed by this method.
