The syntheses of the three isomeric diethyl-and dineopentyltetramethylbenzenes has been accomplished. Differences in the tendencies of the o-isomers as compared to the m-and p- isomers to complex with tetracyanoethylene and 2, 4, 7-trinitrofluorenone have been observed and briefly discussed. New syntheses of compounds containing cyclopropyl rings have been noted in the lithium aluminum hydride, sodium in liquid ammonia, and Raney ...
