Di-n-propyl sulfide [111-47-7] M 118.2, b 141-142 , d 0.870, n 1.449. Washed with aqueous 5% NaOH, then water. Dried with CaCl2 and distd from Na [Dunstan and Griffiths J Chem Soc 1344 1962],... 

Vanadium trichloride or tribromide reacts with thioethers giving [VX3L2] (X = C1 or Br L = SMe2, tetrahydrothiophene or SEt2).288,289 The complex with di-n-propyl sulfide could not be isolated.288 These compounds are oxidized very easily. Solubility, molecular weights and conductance show that they are monomeric and non-ionic. Dipole moments, IR and electronic spectra are consistent with trans trigonal bipyramidal structures. 

A mixture of 14.4 g POCl3 and 13.4 g N-methylformanilide was heated for 10 min on the steam bath. To this claret-colored solution was added 8.9 g of 2,5-dimethoxyphenyl (n)-propyl sulfide, and the mixture heated an additional 25 min...

The mechanism and kinetic aspects of the retro-ene reaction of the allyl n-propyl sulfide and its deuterated derivatives have been studied using four different types of DFT methods with eight different levels of the basis sets.7 The mechanistic studies revealed that the reaction proceeds through an asynchronous concerted mechanism. Theoretical calculations have indicated that the reaction displays a kinetic isotope effect of 2.86 at 550.65 K. 

Other base-borane adducts which can be obtained by base displacement of tetrahydrofuran from tetrahydrofuran-borane include triethylamine-borane (65% yield obtained), morpholine-borane (72% yield obtained), triethylphosphine -borane (91% yield), and di(n-propyl) sulfide-borane (61% yield). Triethylamine-borane and di(n-propyl)sulfide-borane are best purified by vacuum sublimation or distillation from the crude product.

A typical sulfide spectrum that of methyl-n-propyl sulfide is shown in Fig. TheS (2bi) IP is 68450 cm (8.49 eV). At the low frequency end we find a well defined maximum at 45400 cm" and there are shoulders at about 44000 and 46300 cm". The peak is likely to correspond to the 4s 2bi Rydberg transition which is superimposed to a mainly valence-shell type band. (2b i, 3b2 in H2 S). The maximum gives a term value of 23050 cm", acceptable for a 4s band of a sulfur containing molecule of this size. 

Di-n-propyl sulfide heated 45 min. at 115-150° with 4 moles of HNO3 until red-brown fumes cease to evolve di-n-propyl sulfone. 

A mixture of di-n-propyl sulfide and a 50% molar excess of dimethyl sulfoxide heated 8-12 hrs. at 160-175° with distillation of the resulting dimethyl sulfide through a reflux condenser maintained at ca. 40° di-n-propyl sulfoxide. Y 59%.—No sulfone formation takes place and the products are isolated in high purity by simple distillation. F. e. and limitations s. S. Searles, Jr., and H. R.Hays, J. Org. Chem. 23, 2028 (1958).
