This paper describes a new spontaneous copolymerization between the cyclic phosphite of 2-phenoxy-1,3,2-dioxaphospholane and an -keto acid such as pyruvic acid and phenylglyoxylic acid. The copolymerization occurred at temperatures above 100 °C without added catalyst to produce alternating copolymers. During copolymerization, the phosphite Pm in monomer was oxidized to phosphate Pv in the copolymer unit. Thus, it may well be termed "oxidation-reduction copolymerization". A scheme of polymerization involving a phosphonium zwitterion was presented.

A novel synthetic method of l-carvone involving the anodic oxidation of the enol acetate of isopinocamphone in the mixed solvent of methylene chloride-acetic acid as a key step was established. The overall yield of l-carvone from l-α-pinene was 34% and the overall optical yield was quantitative.
