Synthesis and characterization of novel organothiophosphorus compounds: X-ray crystal structure of H3COC6H4P(OC 2H4S)(S) synthesized by a new method

Abstract

Reactions of 2,4-bis(4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane-2,4- disulfide with hydroxy substituted compounds (R-OH) gave rise to the formation of dithiophosphonate compounds 2, 3 and 4 [R-OH: N-(2-hydroxyethyl)-phthalimide, 1-(2-hydroxyethyl)pyridine and 2-(2-hydroxyethyl)pyrrolidine]. Compounds 3 and 4 have been shown in zwitterionic species. The 2,4-bis(4-methoxyphenyl)-1,3,2,4- dithiadiphosphetane-2,4-disulfide was reacted with 2-chloroethanol to give 4-methoxyphenyl-2-sulfido-1,3,2-oxathiaphospholane (5), synthesized by a new method. Nickel and Cadmium complexes (2a and 2c) of 1 were prepared. Compounds were characterized by elemental analysis, IR, 1H-NMR, 31P-NMR, UV/VIS spectroscopies and crystal structure of 5 was determined. The magnetic moment for 2b is 2.97 B.M. © 2006 WILEY-VCH Verlag GmbH & Co. KGaA.
