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.]

In the presence of phosphazene P2-Et base as well as 1,8- diazabicyclo[5.4.0]undec-7-ene (DBU) the coupling of aryl iodides with arenethiois only requires catalytic amounts of CuBr. Under these conditions the reaction can be performed in refluxing toluene to give biaryl thioethers in excellent yields. (C) 2000 Elsevier Science Ltd.
