Ab initio molecular orbital theory at the G 2 level has been used to predict new values for the heat of formation of formaldimine (CH2=NH): ?Hfº0 = 94 ±10 kJ mol-1 and ?Hfº298 = 86 ±10 kJ mol-1.

Orbital Study

Ab initio molecular orbital theory has been used to investigate a series of possible chlorosulfonium ylides to assess the potential for ylide intermediacy in the chlorination of organic sulfides. The majority of optimized structures are best viewed as thionium salts. Only ylide structures in which the putative carbanionic centre bears a powerful anion stabilizer (e.g. cyano or carbomethoxy) survive optimization.

Ab initio molecular orbital theory has been used to deduce the preferred gas-phase conformations of vinyl formate and vinyl acetate. In addition, experimental dipole moments (1030μ/Cm) and molar Kerr constants (1027mK/m5 V-2 mol-1) at 25�C are reported for both molecules as solutes in carbon tetrachloride: vinyl formate (5.07, + 48.1) and vinyl acetate (5.70, + 3.8). The preferred solution-state conformations indicated by the analysis of these results are shown to be consistent with the theoretical predictions.
