| abstract | 1,206,477. Pyrocarbonate esters. SHIONOGI & CO. Ltd. 1 Nov., 1967, No. 49569/67. Addition to 1,130,271. Heading C2C. Esters of pyrocarbonic acid are prepared by reacting 1 mole of a naphthalene sulphonyl chloride of formula in which one or more of the hydrogen atoms may be substituted with a halogen atom or a nitro group with about 2 moles of one or more alkali metal carbonate half esters of general formula MeOCOOR<SP>1</SP> in which Me is sodium or potassium, and R<SP>1</SP> is a C 1 -C 3 alkyl group or an aralkyl group, e.g. a benzyl group. In the examples diethyl pyrocarbonate [O(COOC 2 H 5 ) 2 ] is prepared by reacting (a) naphthalene-1-sulphonyl chloride; (b) naphthalene-2-sulphonyl chloride; (c) naphthalene-1,5-disulphonyl chloride; (d) naphthalene-2,7-disulphonyl chloride; (e) naphthalene-2,6-disulphonyl chloride, and (f) naphthalene-1,3,6-trisulphonyl chloride. |
