Bis(chloromethyl)phosphinic (-phosphinothioic) iso(thio)cyanates add secondary amines to form N-phosphorylated (thio)ureas, which cyclize in the presence of a base to 1,3,4lambda(5)-oxaza(thiaza)phospholines. Phosphorylated ureas obtained by addition of ammonia and primary amines to chloromethylphosphonic (-phosphinic) isocyanates cyclize to give 1,4,2-diazaphospholidines or 1,3,4-oxazaphospholines. Prototropic transformations in the series of 1,3,4lambda(5)-oxazaphospholines were revealed; the electronic and steric structures of the tautomers were studied. Chi oromethylphosphonothioic (-phosphinothioic) isothiocyanates add primary amines to give 1,3,4lambda(5)-thiazaphospholines.

(Chloromethyl)isocyanatophosphonates(-phosphinates) take up phenol to form carbamates whose β-cleavage gives rise to phenyl (chloromethyl)phosphonates(-phosphinates). (Chloromethyl)(thio)phosphinic-(phosphonic) isothiocyanates react with phenol at 20°C in the absence of catalyst to afford phenyl phosphinates(-phosphonates). (Alkylsulfanyl)carbamates formed by addition of thiols to (chloromethyl)iso(thio)cyanastophosphonates(-phosphinates) under the action of an equimolar amount of triethylamine undergo cyclization into 1,3,4-oxaza(thiaza)phospholines.

Addition of phosphoric (phosphonic) acids amides to chloromethyliso(thio)cyanatophosphonates (-phosphinates) gave rise to diphosphorylated ureas or thioureas that under effect of bases underwent cyclization into 1,3,4-oxaza(thiaza)phospholines.

Silicon-containing chloromethylphosphorylated ureas undergo transformation involving evolution of chlorotrimethylsilane and formation of 1,3,4-oxazaphospholes. Their analogs, silicon-containing phosphorylated acylamides, transform in another way, viz. by beta-cleavage to form the corresponding siloxyphosphonates. Quantum-chemical investigation of thermodynamic characteristics of these processes was carried out.

Alcohols and alpha-hydroxyphosphonates undergo the addition to (chloromethyl)phosphonic(-phosphinic) iso(thio)cyanates, yielding phosphorylated (thio)urethanes. The latter undergo cyclization to form, depending on their structure, saturated or unsaturated five-membered P,N,O,S-containin-heterocycles.
