Abstract
The electron impact (e.i.) mass spectrum of N4P4Cl3 shows that the only primary decomposition pathway is due to the loss of a chlorine radical, with formation of the cation (I).
ChemInform Abstract
The electron impact (e.i.) mass spectrum of N4P4Cl3 shows that the only primary decomposition pathway is due to the loss of a chlorine radical, with formation of the cation (I). [N3P3C15]+ is subsequently formed by the loss of the NPClz side group. Upon increasing the N4P4Cl3 vapour pressure to 0.65 torr, oligomerization takes place (with oligomerization degree n of 12). [N4P4C13]′+ (II), formed from N4P3Cl8 under e.i. conditions has a different structure compared to analogous species produced during the gas-phase polymerization process of N3P3Cl6 (III). This result gives further support to the mechanism proposed for the gas-phase oligomerization of (III).
