The EPR spectra of 7-tert-butyl-1-naphthylmethyl and 6-tert-butyl-2-naphthylmethyl radicals, prepared by photolysis of the hydrocarbon with tert-butyl peroxide at -40 deg C, have been analysed by correlation methods: average α(C-H) coupling constants are 15.0 and 15.25 G respectively, in line with the expected relative stabilities of the two radicals and the recently reported stabilization energy for 1-naphthylmethyl.

The novel 10-methylenelongibornane (11), prepared from longicamphor (20), on exposure to BF3*OEt2 generates 4 (R = Me), the methyl homologue of the Berson cation (4, R = H) anchored with the alkyl group at C-10 while traversing a mechanistic pathway entirely analogous to that of longifolene (1) isolongifolene (10, R = H), ending up finally in 8-methylisolongifolene 10, (R = Me).Furthermore, 1,1-dimethyl-7-t-butyltetralin (17, R = Me) has also been isolated from 10 (R = Me) in a second stage rearrangement under more energetic conditions, reminiscent of the transformation isolongifolene (10, R = H) 1,1-dimethyl-7-isopropyltetralin (17, R = H)
