Reactions of 2.2,4,4-Tetrakis(trifluoromethyl)-1.3-dithietane phosphane Gold(1) Complex of a Thiazoline-4-thiolate with KNCS and KNCO - Crystal Structure of a Triphenyl-phosphane Gold(1) Complex of a Thiazoline-4-thiolate2,2,4,4-Tetrakis(trifluoromethyl)-1,3-dithietane (1) reacts with KNCS to yield the potassium salt of 4-mercapto-2,2,5,5-tetrakis(trifluoromethyl)-Δ3-thiazoline (2). An oxidative workup procedure results in the formation of the disulfide 6. The salt 2 reacts with methyl bromoacetate, benzyl bromide, 3-bromo-1-phenylpropene, and 1,3-diiodopropane to form the thioethers 3-5 and 7, respectively. Protonation of 2 results in the formation of the thiolactam 9. Disulfide 6 reacts with Cl2 in the presence of FeCl3 to yield the sulfenyl chloride 8. C-S bond formation (→10) is observed by treating 8 with Me3SiCN. The gold(I) complex 11 is formed from 2 and Ph3PAuCl. 11 crystallizes in the monoclinic space group P21/n and contains a linear P-Au-S unit. The reaction of 1 with KNCO leads after protonation to the perfluorinated lactam 12 and the cyanuric acid derivative 13.
