Synthesis and characterization of spiro-, ansa-, and spiro-ansa-cyclic derivatives of cyclotetraphosphazene with the reactions of pentane-1,5-diol

Abstract

The reactions of octachlorocyclotetraphosphazatetraene, N4P4Cl8 (1) with difunctional aliphatic reagent, HO-(CH2)(5)-OH (3) have aroused a good deal of attention, and four types of products have been realized: one 2-open chain-(1-oxy-5-hidroxy-pentane)-2,4,4,6,6,8,8-heptachlorocylotetraphosphazatetraene, N4P4Cl7[O(CH2)(5)OH] (4); one 2,2-mono-spiro-(1,5-pentanedioxy)-4,4,6,6,8,8-hexachlorocyclotetraphosphazatetraene, N4P4Cl6[O(CH2)(5)O] (5); its isomers 2,4-mono-ansa-((1,5-pentanedioxy)-2,4,6,6,8,8- hexachlorocyclotetraphosphazatetraene (6) and 2,6-mono-ansa-(1,5-pentanedioxy)-2,4,6,6,8,8-hexachlorocyclotetraphosphazatetraene (7); one 2,2,6,6-dispiro-(1,5-pentanedioxy)-4,4,8,8-tetrachlorocyclo- tetraphosphazatetraene, N4P4Cl4[O(CH2)(5)O](2) (8); two isomeric 2,4,6,8-bisansa-(1,5-pentanedioxy)-2,4,6,8-tetrachlorocyclotetraphosphazatetraene (9) and 2,6,4,8-bisansa-(1,5-pentanedioxy)-2,4,6,8-tetrachloro-cyclotetraphosphazatetraene (10); one 4,4,8,8-dispiro-2,6-ansa- (1,5-pentanedioxy)-2,6-dichlorocyclotetra-phosphazatetraene, N4P4Cl2[O(CH2)(5)O](3) (11), one 2,2,4,4,6,6-trispiro-(1,5-pentanedioxy)-8,8-dichlorocyclo-tetraphosphazatetraene, N4P4Cl2[O(CH2)(5)O](3) (12); and a 2,2,4,4,6,6,8,8-tetraspiro-(1,5-pentanedioxy)-cyclotetraphosphazatetraene derivative, N4P4[O(CH2)(5)O](4), (13). The respective structures were deduced by means of elemental analysis, mass spectrum, and P-31, H-1, and C-13 nuclear magnetic resonance spectroscopic investigations. [GRAPHICS] .
