Abstract
Prepn. of cpds. (I) (where each R is opt. same 1-6C alkyl, 3-6C cycloalkyl, aryl, aryl(1-3C) alkyl, aryl, substd. by halogen, 1-3C alkoxy or 1-6C alkyl, heterocyclic ring contg. 5-7 members where 1 or 2 members are O,S or N, dialkyl(1-6C) amino, 2-10C acylamino, 2-8C alkyl- or arylimido, halogen, O-A, S-A, OCOA where A in turn is H,1-6C alkyl, phenyl(1-3C) alkyl, aryl opt.substd. by 1-6C alkyl, 1-3C alkoxy or halogen, or 2 R' gps. together form an aryl ring opt. substd. by 1-3C alkoxy or halogen; n is 0-3; m is 0 or 1; and R is H, 1-6C alkyl, 3-6C cycloalkyl, 3-6C cycloalkyl substd. by 1 or 2 1-4C alkyls, aryl, or phenyl (1-3C) alkyl; and Y is COR, CR(OB)2, COOR or CN, where R is as above and B is 1-6C alkyl, aryl(1-3C) alkyl or both B radicals are alkylidene which together with -O-C-O- to which it is bound forms a 5-7 membered 3-9C alicyclic system). Comprises reacting a phenol deriv. of formula (II) in presence of a Lewis acid with a cpd. R(OCO)mCOY (III). Pref. reaction is effected in aprotic diluent e.g. methylene chloride, nitrobenzene etc. Pref. Lewis acid is a deriv. of tetra-valent -Ti, -Sn, -Zr, trivalent -B, -Al, or pentavalent Mo, and esp. TiCl4. (I) obtd. are intermediate cpds. for e.g. benzofuranones, benzofurons, o-hydroxyaryl alkanoic acids, o-hydroxyaryl malonic acid, arylalkenoic acids, o acylphenols or their derivs. mfr.
