Silina, E. B. published the artcileα-Bromoalkyl isocyanates and their phosphorylated derivatives, Computed Properties of 18791-02-1, the publication is Zhurnal Obshchei Khimii (1989), 59(3), 571-86, database is CAplus.
Reaction of Br3CNCO with ROPX2 (R = Me, Et, X = Cl; R = Bu, X = F) in the presence of FeCl3 gave 27-58% X2P(O)CBr2NCO. Arbuzov reaction of BrCH2CHBrNCO with (R1O)3P (R1 = Et, Me) or with halophosphites (EtO)2PX (X = Cl, F) or EtOPX2 (X = Cl, F) gave (R1O)2P(O)CH(CH2Br)NCO (I; same R1), 40-60% EtOPX(O)CH(CH2Br)NCO (II; same X), or 54-72% X2P(O)CH(CH2Br)NCO (III; same X), resp. Treating I (R1 = Et) and II–III with Et3N gave 48-75% ethylene isocyanates (EtO)n(X)2-nP(O)C(:CH2)NCO (IV; n = 0-2; X = Cl, F), which when treated with Br2 gave 33-68% (EtO)n(X)2-nP(O)CBr(CH2Br)NCO (V). Reaction of III (X = Cl) or IV (n = 0; X = Cl) with R2OH (R2 = Me, Et) and Et3N gave 73-87% carbamates (R2O)2P(O)C(:CH2) NHCO2R. III (X = F) and IV (n = 0, X = F) reacted with PhNH2 to give 65-81% anilides F2P(O)CH(CH2Br)NHCONHPh and F2P(O)C(:CH2)NHCONHPh, resp. 1H, 19F, and 31P NMR spectra of III–V are discussed.
