Treatment of NiCl2(dme) and NiBr2(dme) (dme = dimethoxyethane) with 2 equiv of LiOR (OR = OCtBu2Ph) forms the distorted trigonal planar complexes [NiLiX(OR)2(THF)2] (THF = tetrahydrofuran)
Olefins from Crowded Carbonyl Compounds with tert-Butyllithium (tert-Butylmagnesium Chloride)/Thionyl Chloride. Study of Carbocationic Reaction Intermediates and Rearrangement-Cleavage under Stable Ion Conditions Using 13C NMR Spectroscopy

Crowded carbonyl compounds when reacted with tert-butyllithium or tert-butylmagnesium chloride followed by thionyl chloride treatment give in an one-pot reaction olefins in good to excellent yields.In the case of highly crowded tertiary systems the reaction occurs either by rearrangement followed by the loss of a tert-butyl group (as isobutylene) or rearrangement accompanied by deprotonation, indicating the carbocationic nature of the process.The nature of the intermediate carbocation and their cleavage-rearrangement process was probed in SbF5/SO2ClF solution of thecorresponding alcohols under stable ion conditions using 13C NMR spectroscopy.
The retro Grignard addition reaction revisited: The reversible addition of benzyl reagents to ketones

The Grignard addition reaction is known to be a reversible process with allylic reagents, but so far the reversibility has not been demonstrated with other alkylmagnesium halides. By using crossover experiments it has been established that the benzyl addition reaction is also a reversible transformation. The retro benzyl reaction was shown by the addition of benzylmagnesium chloride to di-tert-butyl ketone followed by exchange of both the benzyl and the ketone moiety with another substrate. Similar experiments were performed with phenylmagnesium bromide and tert-butylmagnesium chloride, but in these two cases the Grignard addition reaction did not show any sign of a reverse transformation.
Barriers to Internal Rotation in Neopentylbenzenes Substituted on the Benzyl Group. A 13C NMR Band Shape Study
Andersson, Sven,Drakenberg, Torbjoern
, p. 730 - 744 (2007/10/02)
Two series of neopentylbenzenes with one or two substituents on the benzyl group have been synthesized.In one series the substituents were H, F, Cl, Br, I, OCH3, OCOCH3, OSi(CH3)3, CH3 and CH2CH3, and in the other OH and R R = H, CH3, CH2CH3, (CH2)3CH3,
