摘要：

1,1-Dibenzyl-2,2-dimethylpropan-1-ol 1 shows a coalescence phenomenon in its C-13 solid state CP MAS NMR spectrum consistent with slowing of rotation of the tert-butyl group about the C(1)-C(2) bond with an activation energy of 13.1 kcal mol-1 (1 cal = 4.184 J), 4 kcal mol-1 higher than in solution.
