Phenylene Diamine

In a short paper recently submitted to the Royal Society, I pointed out the existence of two aromatic diamines, both represented by the formula C 6 H 8 N 2 = (C 6 H 4 )'' H 2 H 2 } N 2 , and closely resembling each other, but differing in some of their fundamental characters to such an extent that I did not hesitate to assert their individuality, and to distinguish them as alpha-pheny-lene-diamine and beta-phenylene-diamine. The existence of two closely allied bodies among the diatomic derivatives of the phenyl-series very naturally suggested the idea of searching for two similarly related monatomic bases of the same group, and accordingly I undertook during the last week a careful comparison of specimens of aniline prepared by different piocesses. This com parative study is still incomplete, but I beg leave to record even now an observation which appears to merit the attention of chemists.

Several known volatile closo-carboranes (1,5-C2B3H5, 1,6-C2B4H6, 2,4-C2B5H7, 1,10-C2B8H10) and their alkyl derivatives and ten new alkyl derivatives of these carboranes were identified from the thermal gas-phase flash reactions of B2H6, B3H7CO and B4H10 with ethyne, propyne and but-2-yne. In addition, nido-C4B2H6 and its methyl derivatives were obtained from B2H6-alkyne flash reactions. All carboranes found in these high-energy reactions are the most thermally stable isomers of their class. The non-isolable borane {B3H7} is suggested as the initiator in all thermal flash reactions reported here.
