Preliminary studies of the spectral properties of phosphabensene (phosphorin) ,? and arsabenzene (arsenin) 2 have emphasized their similarities to 2-6 pyridine . Recently we reported the gas phase dipole moment of phosphabenzene as 1.54D5 and that of arsabenzene as l.10D6. The magnitude is conside
## Abstract The He(II) photoelectron spectra of phosphabenzene **2** and arsabenzene **3** yield additional ionization energies in the region 17 to 20 eV. The relative intensity changes of the first three bands, compared to their relative intensities in the He(I) spectra, provide support for the pr
The reaction of methyllithium with 2-chlorobicyclo[2.2.1]heptene (j,) has been reported to produce P-methylbicyclo[2.2.l]heptene (x) in 73% yield.2 This appeared to be a unique example of a substitution of a vinylic chloride by an alkyl group through reaction with an organolithium reagent. Whereas,
