摘要:Squarylium compounds of the formula: n wherein Q 1 and Q 2 are each independently a pyrylium, thiopyrylium, selenopyrylium, benzpyrylium, benzthiopyrylium or benzselenopyrylium nucleus, and R 1 and R 2 are each independently an aliphatic or cycloaliphatic group, can be prepared by reacting a squaric acid derivative of the formula: n with a compound of the formula Q 2 CH 2 R 2 in the presence of a base. The derivatives of Formula II may be prepared by condensing a 2,3,4,4-tetrahalocyclobut-2-en-1-one with a compound of the formula Q 1 CH 2 R 1 in the presence of a base to produce a compound of the formula: n wherein Q 1 and R 1 are as defined above, and X represents chlorine or bromine, and hydrolyzing the compound of Formula III. Alternatively, the derivatives of Formula II may be prepared by reacting a diester, monoacid chloride monoester or diacid chloride of squaric acid with a compound of the formula Q 1 CH 2 R 1 in the presence of a base, followed by hydrolysis of the resultant monoacid chloride or monoester derivative of the compound of Formula II to the parent compound.

标 题 :An improved synthesis of tetrakis (dihydro carbylamino) phosphonium halides

摘要:An improved, commercially viable process for synthesizing tetrakis(dihydrocarbylamino)phosphonium halides in the absence of oxigen is described. When reacting a tris(dihydrocarbylamino)phosphinimine with a halohydrocarbon and an aqueous solution of a source of hydroxide ion to form a tetrakis(dihydrocarbylamino)phosphonium halide, a combination of increased pressure and liquid organic medium is used. The advantages gained by operating in this fashion include shorter reaction times and the need for only about stoichiometric or slightly more than stoichiometric amounts of halohydrocarbon and source of hydroxide ion.
