Supramolecular systems based on poly(ethyleneimines) and calix[4]resorcinarenes with alkylphosphonate fragments. Aggregation and catalytic activity

Aggregation in poly(ethylenimine)-calix[4]resorcinarene-water-DMF systems was studied by the methods of conductometry and dynamic light scattering. The sizes (radii) of the aggregates formed and the critical micelle concentrations were determined. The catalytic activity for these systems in the hydrolisys of phosphorus acid esters was shown.

Reactions of P(III) thiobenzyl esters with methyl iodide

The reactions of S-benzyl diphenylthiophosphinite and 2-benzylthio-4,5-benzo-1,3-dioxaphospholane with methyl iodide have been examined. In contrast to the oxygen analogs, the reaction occurs under mild conditions, and does not give Arbuzov reaction products.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 12, pp. 2856–2857, December, 1991.     

Synthesis of phosphorus (silicon,tin)-containing derivatives of mercaptoketenes and some of their properties

Some newS-phosphorylated,S-silylated, andS-stannylated derivatives of -mercaptoketones were obtained. The reactions of some of these compounds induced by the temperature and by molecular oxygen as well as the phosphorylation of the Si- and Sn-containing derivatives were studied.Translated fromIzvestiya Akademii Nauk.

Phosphorus containing pyrydoxal azomethines and alkoxyfuropyridines of salt structure

The reaction of azomethines of pyridoxal or alkoxyfuropyridines with phosphorus acids produces new salt derivatives.     

Phosphorylation of pyridoxal azomethines. Synthesis of phosphorus containing azomethines and furopyridines

New O-phosphorylated pyridoxal derivatives have been synthesized through the reaction of azomethines with Р^V acid chlorides. 2-Chloro-2-thioxo-5,5-dimethyl-1,3,2-dioxaphosphinanes and diethylchlorothiophosphate have been employed as phosphorylating agents. Regardless of the nature of the phosphorylating agent, the reaction is regioselective at phenolic hydroxyl group. The structure of final products is determined by the nature of the substituent at the nitrogen atom. If R is alkyl or cycloalkyl group, the products of the reaction represent phosphorylated pyridoxal imines, whereas phosphorylated furopyridines are formed in the case R is aryl substituent.
