## Abstract The photochemical behaviour of 2βBromoβ4,4βdimethylβ2βcyclohexenone (1) was studied in 2βpropanol and cyclohexane. In both solvents (nβΟ\*)βexcitation followed by intersystem crossing leads to population of a lowβlying triplet (T~1~) state, which can be quenched by 1,3βcyclohexadiene bu

β¦ Synopsis
Various studies, including conductivity, surface tension, compressibility, emf-measurement, vapour phase osmometry, solubility and density, have been performed on [PNP]'-halides in water and methanol. It is concluded that these salts are very well dissociated in methanol while in water, [PNP]+Cl-, the most soluble salt, appears to have a critical micelle concentration, 'cmc-value', at -0.005 mol 1-l . References 1 [ PNP]+ designs the bis(triphenylphosphine)iminium cation, [ (PhaP)zN]+.

## Abstract The parameters which influence the inverted wave appearing in the reverse (oxidation) sweep in the cyclic voltammogramme of the title compound **1** are discussed in detail. The inverted wave is due to the interaction of the reduction products of **1** with the electrode and the electro
