In order to study radical cation rearrangements, the species generated by y-irradiation of 1,2-diphenyl-3,3,4,4-tetramethylcyclobutene (CB) and 3,4-diphenyl-2,5-dimethyl-2,4-hexadiene (BD) in frozen Freon solutions were studied by monitoring their EPR and visible absorption spectra. The optical and
## Abstract The triazaphosphole __1__ adds sulfur along with HCl or H~2~S to yield, respectively, the dihydrotriazaphosphole thiochloride __4__ and sesquisulfide __5__ (two diastereomers). In pyridine solution, __1__ adds sulfur alone to yield the trimer of a triazaphosphole monosulfide __7__. Its
1,3-Bis(4-vinylnaphthyl)propane and 1-(4-vinylnaphthylj-3-(p-vinylphenyllpropane, were cyclocodimerized with indene to afford indenyl-substituted [3\_3](1,4)naphthalenophanes and [3.3]paracyclo(l,4)naphthalenophanes. Syntheses of [3.3](l,4)naphthalenophane2
