Abstract The mass spectral fragmentations of various thioformaldehydes, 1,3,5‐trithiacyclohexane, 1,3,5,7‐tetrathiacyclooctane, 1,3,5,7,9‐pentathiacyclodecane and a polymeric form (CH 2 S) x have been examined. The principal features of the spectra are reported. The fragmentation occurred by fracture of the ring in the cyclic compounds with or without rearrangement.
The monoacids derived from trithiane, tetrathiocane, and pentathiecane, C 3 H 5 S 3 X (X = CO 2 H, COSH, CS 2 H), C 4 H 7 S 4 X (X = CO 2 H, CS 2 H), and C 5 H 9 S 5 X (X = CO 2 H, CS 2 H) and the lithium salts C 3 H 5 S 3 SO 2 Li, C 4 H 7 S 4 SO 2 Li, and C 5 H 9 S 5 SO 2 Li have been prepared and their reactions studied. The corresponding esters C 3 H 5 S 3 CO 2 R (R = CH 3 , C 2 H 5 , n-C 3 H 7 , i-C 3 H 7 n-C 4 H 9 , n-C 5 H 11 ), C 3 H 5 S 3 COSCH 3 , C 4 H 7 S 4 CO 2 R (R = CH 3 , C 2 H 5 ) and the ammonium salts, C 3 H 5 S 3 CO 2 NH 4 , C 3 H 5 S 3 CS 2 NH 4 , C 3 H 5 S 3 CS 2 N(n-Bu) 4 , C 4 H 7 S 4 CO 2 NH 4 , (C 4 H 7 S 4 CO 2 ) 2 (Me 2 NHCH 2 ) 2 , and C 5 H 9 S 5 CO 2 NH 4 have been isolated. The reactions of the acid anion with various metal ions have been investigated. Nuclear magnetic resonance, mass, and infrared spectroscopic data of some of the products are reported.
The new compounds n-Bu 3 SnSR, n-Bu 2 Sn(SR) 2 , where R = Me, Ph, or C 6 F 5 , and Ph 3 SnSC 6 F 5 have been prepared and characterized. The fracture of the Sn—S bond with iodine has been examined and affords a quantitative method for analysis of compounds containing a Sn—S bond. The 1 H and 19 F n.m.r. have been studied; frequencies characteristic of the C 6 F 5 S— group in the infrared spectra have been tabulated.
Giving a critical picture of the different aspects of fluorine, this handbook of inorganic and organometallic chemistry covers perfluorohalogenoorgano compounds of main group elements.
Abstract Die direkte nucleophile Substitution der Pentafluorphenylverbindungen (I) mit Natriummethylmercaptid in einem siedenden Gemisch von Äthylenglykol/Pyridin liefert die Methylmercaptoderivate (II)‐(IV) sowie (VI) und (VII) in verschiedenen Ausbeuten.
Acetyl heptachlorodialuminate has been prepared from acetyl chloride and aluminium chloride in liquid hydrogen chloride. Conductometric titrations of tetra-alkylammonium chlorides against aluminium chloride in acetyl chloride as a solvent have been carried out and end-points found corresponding to the formation of both heptachlorodialuminate and tetrachloroaluminate ions.
