First X-ray crystallographic study of a benzyl cation, cumyl hexafluoroantimonate(V), and structural implications

The crystal structure of the cumyl cation (1; 2-phenyl-2-propyl cation) has been determined at -124°C (as hexafluoroantimonate, 1.SbF6; R1 = 0.0502, wR2 = 0.1054). The cation 1 is nearly planar and has a short C+-C(ipso) bond (1.41(2) A?) and bond lengths in the phenyl ring which agree with strong benzylic delocalization. The weak but distinct shortening of the C+-CH3 bonds by 0.025(12) A? indicates weak C-H hyperconjugation. Nearly all H atoms are involved in H...F contacts to SbF6 anions, and one close C+...F contact (3.11 (2) A?) is observed. The phenyl rings form infinite stacks and are shifted against each other in the stack.

Desulfurative Chlorination of Alkyl Phenyl Sulfides

The chlorination of readily available secondary and tertiary alkyl phenyl sulfides using (dichloroiodo)benzene (PhICl2) is reported. This mild and rapid nucleophilic chlorination is extended to sulfa-Michael derived sulfides, affording elimination-sensitive β-chloro carbonyl and nitro compounds in good yields. The chlorination of enantioenriched benzylic sulfides to the corresponding inverted chlorides proceeds with high stereospecificity, thus providing a formal entry into enantioenriched chloro-Michael adducts. A mechanism implying the formation of a dichloro-λ4-sulfurane intermediate is proposed.

Direct halogenation of alcohols with halosilanes under catalyst- and organic solvent-free reaction conditions

A chemoselective method for the direct halogenation of different types of alcohols with halosilanes under catalyst- and solvent-free reaction conditions (SFRC) is reported. Various primary, secondary and tertiary benzyl alcohols and tertiary alkyl alcohols were directly transformed to the corresponding benzyl and alkyl halides, respectively, using chlorotrimethylsilane (TMSCl) and bromotrimethylsilane (TMSBr).
