Page 9, (2010/02/07)
The invention relates to a new method of preparation of derivatives of piperidinyl butylphenylacetic acids. The compounds are histaminically active. The substances are prepared by Grignard reaction of alkylhalohydrins and suitably substituted aromatic aldehydes. The resulting diols are subjected to subsequent substitution reaction.
Process for the production of cyclic sulfonium salts
-
, (2008/06/13)
A process for the production of a 5-7 membered ring cyclic sulfonium salt compound, including a 5-7 membered ring cyclic sulfonium salt compound having a non-nucleophilic anion, is described. Members of the latter group are potentially useful as initiators for cationic polymerizations. The process comprises reacting a 1.4-, 1.5-, or 1.6-diol compound or a 5-7 membered ring cyclic ether compound with a mercapto compound and a strong protonic acid yielding the cyclic sulfonium salt compound. Some compounds described are also novel compounds per se.
