Synthesis and Spectroscopy of N3P3X5OCHCH2(X = Cl, F, OCH3, OCH2CF3, N(CH3)2) and N3P3X4(OCHCH2)2(X = Cl, N(CH3)2). Correlations of Ultraviolet Photoelectron Spectroscopy and Nuclear Magnetic Resonance Data to Electronic and Geometrical Structure

“…These fractions were combined to give 2.44 g (11.2% of theory) of a colorless liquid, bp (68−72 °C). This compound has been previously prepared using a different method and was identified from the reported 1 H and 31 P NMR data. , …”

“…The reactions of enolate anions with halocyclophosphazenes lead to a wide range of vinyloxycyclophosphazenes. − We have explored the reactions of the simplest of these species, i.e., the enolate of acetaldehyde, in detail and reported the synthesis of the following derivatives: N 3 P 3 Cl 6 - n (OCHCH 2 ) n ( n = 1−6), ,, N 3 P 3 F 6 - n (OCHCH 2 ) n ( n = 1−5), and N 4 P 4 Cl 8 - n (OCHCH 2 ) 2 ( n = 1, 2) . Our interest in these materials has been focused on two areas: new organofunctional phosphazene monomers that can be converted to carbon chain polymers with cyclophosphazenes as substituents , and questions involving regio- and stereochemical control in the substitution reactions of cyclophosphazenes .…”

Regio- and stereochemical control in substitution reactions of cyclophosphazenes

“…125 An extensive series of (vinyloxy)cyclophosphazene derivatives has been prepared from reaction of the halophosphazene with the lithium enolate of acetaldehyde. 15,[126][127][128] The reaction leading to the chlorotrimer derivatives, N3P3Cl6_n(OCH=CH2)n (n = 1-6) follows a predominant, but not exclusive, nongeminal pathway with a cis preference being observed in the di-126 and trisubstituted128 products. 126 The corresponding reaction of the fluoro trimer gives rise to the series N3P3F6_n(OCH=CH2)" (n = [1][2][3][4][5] which is exclusively nongeminal.…”

“…126 The corresponding reaction of the fluoro trimer gives rise to the series N3P3F6_n(OCH=CH2)" (n = [1][2][3][4][5] which is exclusively nongeminal. 127 The tetrameric derivatives N4P4Cl8_n(OCH=CH2)" (n = 1,2) have been prepared and at the stage of disubstitution, all isomers are obtained but the major component is the 2,4 derivative with the cis isomer predominating.128 Preferential formation of the 2,4 regioisomer is unique in reactions of N4P4C18.…”

Poly[(vinyloxy)cyclophosphazenes]

“…To precisely examine all of these effects and to focus on systems in which inorganic ring system plays a significant or dominate role in determination of properties and be-havior of the polymers in question, we have focused on systems wherein the insulating function is a single oxygen atom. Monomers exhibiting this structure are conveniently available from the reactions of enolate anions with cyclophosphazenes [15][16][17][18] and the reactions of these derivatives with various nucleophiles. 19 In this paper, we explore the polymerization of vinyloxycyclophosphazenes and the properties of the resulting polymers.…”
