Tetrathioorthocarbonate as a C4+ Synthon. Nickel-catalysed Alkylative Alkenation of Tetrathioorthocarbonate with Grignard Reagents

The nickel-catalysed cross-coupling reactions of tetrathioorthocarbonate 1 with Grignard reagents give the corresponding substituted alkenes in moderate to good yields; the reaction demonstrates the first example of using tetrathioorthocarbonate as a C4+ synthon.

MARKED EFFECTS OF RING SIZE ON THE CORRELATED ROTATION OF THE CYCLOALKYL GROUPS OF 1,1-DICYCLOALKYLMETHYLENECYCLOALKANES

Correlated rotation of the cycloalkyl groups has been observed by 13C NMR for the title compounds containing six-, seven-, or eight-membered rings.The ΔH(excit.) value increases with the increase in the ring size, attaining 79.5 +/- 2.1 kJ mol-1 when all the three rings are eight-membered.Molecular mechanics calculations indicated that the magnitude of internal angles is a major contributing factor.
