Kinetics and mechanism of unimolecular heterolysis of carcass compounds. XV. The nature of solvation effects in heterolysis of 2-bromo-2-phenyladamantane in dipolar aprotic solvents

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

13C, 1H Spin-Spin Coupling. X - Norbornane: A Reinvestigation of the Karplus Curve for 3J(13C, 1H)

13C, 1H spin-spin coupling constants over one, two and three bonds were measured from the 100 MHz 13C NMR spectra of deuteriated isotopomers of norbornane-d1 (1) and fenchane-2-d1 (2) and also of a number of monodeuteriated alkyl-substituted adamantanes.The magnitudes of the corresponding J(13C, 1H) values derived from these data by application of the well known relationship J(X, 1H) = 6.5144J(X, 2H) are discussed with respect to the structural data for the hydrocarbons, which were taken from force field calculations with the Allinger MM2 method.In particular, the dihedral angle dependence and the Karplus curve for 3J(13C, 1H) are investigated.Coupling constants calculated by the FP-INDO method are compared with the experimental data, and the effect of substitution by additional CC bonds in α-, β- and γ-positions of the 13C-α-C-β-C-γ-H bond fragment is elucidated.If substituent effects that arise through branching and methyl substitution in 1 and 2 are taken into account for dihedral angles Φ > 90 deg, one derives 3J(13C, 1H) = 4.50 - 0.87 cos Φ + 4.03 cos 2Φ with J(0 deg) = 7.7, J(60 deg) = 2.0 and J(180 deg) = 9.4 Hz.

Thermolabile Hydrocarbons, XX. Synthesis, Structure, and Strain of Sym. Tetraalkyl-1,2-diarylethanes

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.
