Heterolysis kinetics of 2-bromo-2-phenyladamantane in MeCN,γ-butyrolactone, sulfolane, and cyclohexanone were studied with verdazyl method. The rate is described by an equation w = k[RBr], and the reaction proceeds by SN1 mechanism. The decreas

The syntheses of 18 1,1,2,2-tetraalkyl-1,2-diarylethanes 1 - 4 by dimerisation procedures starting with 10 - 13 are reported.In the absence of p-substituents X and with increasing alkyl side chains the α,p-dimers 6 or their aromatic counter parts 7 are obtained besides or instead of 1.The relationships between strain enthalpy Hs, bond lengths, bond angles, torsional angles, and rotational barrier are discussed on the basis of force field calculations.They are supported by two additional experimental structure determinations by X-ray diffraction.
