N. Kuhn et al., SELECTIVE REDUCTION OF SULFURIC CHLORIDE - THE STRUCTURE OF THE CHLOROSULFITE ION, Journal of the Chemical Society, Chemical Communications, (19), 1994, pp. 2283-2284
The stable salt 2 is obtained from the reaction of SO2Cl2 with the imi
dazol-2-ylidene 1; the pyramidal structure of the chlorosulfite anion
is confirmed both by X-ray structure and MO calculation.
