Balczewski, Piotr published the artcilePhosphorus containing radicals. 1. Free radical reaction of α-haloalkylphosphonates with alkenes and alkynes: a new approach to modified phosphonates, Product Details of C5H12BrO3P, the publication is Synthesis (1995), 392-6, database is CAplus.
A new approach to the synthesis of phosphonates functionalized in the α- and γ-phosphonate positions by alkyl, ethoxy, butoxy, acetoxy, acetyl and cyanide groups and allylphosphonate is described. It is based on the radical reaction of α-halosubstituted phosphonates (EtO)2P(O)CHR1X (1, R1 = H, Me, X = Cl, Br, I) with the terminally unsubstituted alkenes (1-heptene, ethoxyethene, butoxyethene, acetoxyethene, acrylonitrile, Me vinyl ketone) and alkyne (hept-1-yne). The reaction involving the tin hydride method (Bu3SnH/AlBN) was more effective with alkenes than with alkynes (40-72% vs. 20-30%). With electron-rich alkenes, chloro- and bromomethylphosphonates 1 (X = Cl, Br) gave higher yields than iodomethylphosphonate 1 (X = I). Di-Et methylphosphonate, as a reduction product of 1, accompanied in the above reactions. The yield of di-Et methylphosphonate could be reduced by optimizing the reaction conditions.
Synthesis published new progress about 66197-72-6. 66197-72-6 belongs to bromides-buliding-blocks, auxiliary class Aliphatic Chain, name is Diethyl (bromomethyl)phosphonate, and the molecular formula is C5H12BrO3P, Product Details of C5H12BrO3P.
