Abstract Two series of neopentylbenzenes with one or two substituents on the benzyl group have been synthesized. In one series the substituents were H, F, Cl, Br, I, OCH 3, OCOCH 3, OSi (CH 3) 3 CH 3 and CH 2 CH 3, and in the other OH and R [R [BOND] H, CH 3, CH 2 CH 3,(CH 2) 3 CH 3, CH (CH 3) 2 and C (CH 3) 3]. Barriers to internal C math image [BOND] C math image and C math image [BOND] C math image rotation have been estimated by 13 ...
