The infrared spectra of cis and trans 1,2-dimethyl-, 1,2-diethyl-, 1,2-methylethyl-and 1,2-methylpropylcyclopentane isomers have been recorded in the frequency range from 400 to 3000 cm –1 . Assignments of some fundamentals are possible in a few cases when comparison of the spectra with...
The mechanism suggested is addition of two molecules of hydrazines in the 5 position followed by a transannular reaction to the 7 position for hydrazine and to the 3 and 7 position for phenylhydrazine.A. HasnaouiJ.-P. LavergnePh. Viallefont...
