Abstract
IN a recent issue of NATURE (August 21, p. 283) attention is directed to some, lengthened chain compounds of sulphur described by Sir P. C. Rây and : K. C. Bose-Rây (J. Indian Chem. Soc., 1926, 3, 75) as products of the interaction of dithioethylene glycol and ethylene dibromide. Of the three points, which are emphasised by the authors, namely, (a) the isolation of a compound containing bromine, (b) the high molecular weight of this compound, and (c) its formulation as having a long chain structure, two cannot be regarded as new, whilst the evidence for the third is unconvincing. For the very similar reaction of ethylene dibromide with potassium sulphide was shown by Crafts so long ago as 1863. (Annalen, 128, 220) to yield such substances of presumably high molecular weight containing 12-28 per cent, of bromine and with a ratio of C:H = 1:2. Moreover, the suggestion that these substances have a long open chain structure has recently been put forward on more than one occasion (J. Chem. Soc., 1921, 119, 1861; 1925, 127, 2676).
