Treatment of acyclic as well as polycyclic tertiary mono- and dihydroxy hydrocarbon derivatives with thiourea in the presence of hydrobromic and acetic acid represents a convenient one-step route to the respective tertiary thiols and dithiols. This procedure was used for the preparation of diamondoid thiols of diamantane, triamantane, [121]tetramantane, and others that are prospective nanoelectronic materials.
The Conformational Behaviour of 10-Substituted Spirodecanes
Wolff, J. Jens,Frenking, Gernot,Harms, Klaus
, p. 551 - 561 (2007/10/02)
The conformational behaviour of 10-X-substituted 1,4-dioxa- and 1,4,6-trioxaspirodecanes 1-4 has been studied by 13C-, 19F- and 1H-NMR spectroscopy.Two X-ray analyses of (2a,e) are presented, and their implications to cleavage reactions of chiral acetals are discussed.Participation of twist boat forms in the conformeric equilibrium of at least 1c has been made plausible by observing 13C, 19F-NMR coupling constants.The ratios of axial to equatorial conformers in 1-4 have been calculated by molecular mechanics.
The Invention of New Radical Chain Reactions. Part 11. A New Method for the Generation of Tertiary Radicals from Tertiary Alcohols
Barton, Derek H. R.,Crich, David

A convenient procedure for the radical deoxygenation of tertiary alcohols has been invented using the double half esters of oxalic acid with the t-alcohol and N-hydroxypyridine-2-thione.Decomposition of this type of ester in the presence of 1,1-dimethylethane- or (better) 1,1-diethylpropane-thiol gave the corresponding hydrocarbons in good yield.It has been shown that the oxalate fragmentation is not concerted, but involves a stepwise loss of carbon dioxide.Tertiary alcohols are also a convenient source of radicals for addition to siutable alkenes with formation of quaternary centres.
