Twenty-four aryl benzyl sulfides, diaryl sulfides and dibenzyl sulfides were synthesized by four methods and characterized by 1H NMR, FT-IR and Gas chromatography. The reaction conditions of different synthesis methods were studied from the aspects of time, solvent, base and dispersant. The molecular structures of benzylphenyl sulfide (2S), (4-tert-butylbenzyl)(4-methylphenyl) sulfide (4S), (4-methylbenzyl)(4-methylphenyl) sulfide (9S), di(4-methylphenyl) sulfide (11S), (3,5-dimethylphenyl)(4-methyl phenyl) sulfide (15S), and dibenzyl sulfide (19S) [22] have been determined by single-crystal X-ray crystallography. Compounds 2S and 15S crystallize in the monoclinic space group P21/c, with a = 12.278(3), b = 15.894(3), c = 5.6056(11) ?, β = 94.532(2)°, and Z = 4 for 2S, and a = 9.800(9), b = 7.950(7), c = 16.690(15) ?, β = 100.890(12)°, and Z = 4 for 15S. The unit cell of 4S has a triclinic Pī symmetry with the cell parameters a = 6.0436(10), b = 8.7871(14), c = 15.535(2) ?, α = 81.921(2)°, β = 81.977(2)°, γ = 80.889(2)°, and Z = 2. Compounds 9S and 11S both crystallize in the orthorhombic space group P212121, with a = 6.188(3), b = 8.041(4), c = 26.005(14) ?, and Z = 4 for 9S, and a = 5.835(2), b = 8.010(3), c = 25.131(9) ?, and Z = 4 for 11S. Graphic Abstract: Twenty-four aryl sulfide compounds with different substituents were synthesized and characterized, and the molecular structures of six different sulfide compounds have been determined by single-crystal X-ray crystallography.[Figure not available: see fulltext.]
Zinc-catalyzed regioselective addition of alkyl thiols to alkenes via anion or radical reactions

Zn-catalyzed reactions of alkenes with alkyl thiols could afford alkyl sulfides regioselectively. When the ZnI2- catalyzed hydrothiolation of alkenes was achieved using alkyl thiols at 100 °C, Markovnikov-type alkyl sulfides were obtained in excellent yields without the formation of linear products. To the contrary, Zn(OAc)2- catalyzed reaction gave rise only to anti-Markovnikov-type products regioselectively. The reaction proceeded via a radical process.
