Synthesis of new class of phosphorus and oxygen macroheterocycles

New class of macrocyclic aryloxy phosphoranes (10a–d, 11a–d, 12a–d) were prepared by reactants the bifunctional synthons (7–9) with bis(2/3-chloroalkyl)phenyl triester of phosphoric acid (5a–d) in the presence of aq.NaOH in n-BuOH in moderate yields. Their chemical structures were established by analytical and spectral (IR, 1H, 13C and 31P and Mass) data.

Synthesis of 6-Alkyl Carbamato/Alkyl Thiocarbamato-2,10-dichloro-12-trichloromethyl-12 H -dibenzo[d,g][1,3,2]-dioxaphosphocin 6-Oxides

6-Alkylcarbamato/alkylthiocarbamato-2,10-dichloro-12-trichloromethyl-12 H -dibenzo [d,g][1,3,2]-dioxaphosphocin 6-oxides have been synthesized by the condensation of 2,2-bis(2-hydroxy-5-chlorophenyl)-1,1,1-trichloroethane with dichlorophosphinyl carbamates of different alcohols/thiols in the presence of triethylamine in dry toluene and were characterized by different spectral studies.
