THE ROTATIONAL AND VIBRATIONAL SPECTRA, STRUCTURE AND DIPOLE MOMENT OF 1,3-DIOXOLE-2-THIONE

Rotational and centrifugal distortion constants are determined for the ground state and several excited states of the lowest vibrational mode of 1,3-dioxole-2-thione, the "envelope" ring-bending mode.The structure of the molecule is planar.The A-constant is 1percent larger than that of 1,3-dioxole-2-one (vinylene carbonate), which indicates small changes in ring-geometry on substituting C=S for C=O.The dipole moment of 1,3-dioxole-2-thione deduced from Stark-effect measurements is (1.60 +/- 0.02)*E-29 Cm (4.81 +/- 0.06 D).IR and Raman spectra lead to a complete analysis of the normal modes of vibration, based partially on a normal coordinate calculation.

Dication Ethers and Related Compounds, 1. On Dication Chalkogenides and Dichalkogenides

Reaction of N,N-, N,S-, S,S-, and O,O-substituted thiones 4a-f or selones 6a-c with trifluoromethanesulfonic anhydride leads to dication disulfides 5a-f or diselenides 7a-c, resp.No dication sulfides or selenides are obtained whose formation would parallel the reactivity of the corresponding urea derivatives.This class of dications (14, 15) is, on the other hand, accessible by the reaction of dication ethers 13 with thiones 4 or selones 6. 1H and 13C NMR data of the dication dichalkogenides and chalkogenides are compared with each other.
