| dc.description | Large, sterically demanding groups have facilitated preparation of many compounds containing low coordinate environments for main group elements. Assessment of strain energy for molecules containing main group elements in low coordinate environments indicates that thermodynamic stability with respect to oligomers and structural alternatives involving higher coordination numbers is imposed by large substituents. These results help rationalize some of the observations made in recent years. | en_US |
| dc.description | The phosphoazonium cation (Mes$\sp*$NP) $\sp+$ (Mes$\sp*$ = 2,4,6-tri-tert-butylphenyl) is a phosphorus analogue of the diazonium cation, and its reaction with hydridic bases results in the formation of aminophosphenium cations. A mechanism is proposed, and the first example of an oxyphosphenium cation is reported. The first arene complexes of phosphorus (shown in figure) have been isolated and comprehensively characterized, and they represent stable models of $\pi$-complex intermediates in electrophilic aromatic substitution. Spectroscopic studies indicate that the coordination geometries observed in the solid are maintained in solution.(DIAGRAM, TABLE OR GRAPHIC OMITTED...PLEASE SEE DAI) | en_US |
| dc.description | A convenient synthesis of rare monomeric trihalogenophosphine imides (Mes$\sp*$N = PX$\sb3$) is described, and attempts to prepare stable methylenephosphonium cations have resulted in the discovery an unprecedented ring expansion reaction for methylenephosphoranes. The factors governing the structure of SbCl$\sb3$ arene complexes are discussed. | en_US |
