| titleOfInvention | PROCESS FOR PRODUCING PHOSPHONIC ACID DIHALOGENIDES |
| abstract | Title cpds. of the formula: (where R is 1-18C alkyl, 4-8C cycloalkyl, 2-8C alkenyl, or 6-8C aryl, aralkyl, or alkyl-aryl, R opt. being substd by Cl, Br, CN, or lower acyloxy; and X is halogen) are prepd. by reacting phosphonic acid derivs. of the formula: R-P(O)(OR1)(OR2) (where R1 is H, a monovalent cation, 1-12C alkyl or haloalkyl or 4-8C cycloalkyl, and R2 is H or a monovalent cation) or corresponding pyrophosphonic acid derivs. or thio analogues of these derivs. with acid halides of the formula (CO)nX2 (where n is 1 or 2) in the presence of (a) cpds. contg. >=1 tertiary or quaternary N- or P-atom at least 3 valences of which are linked to is not >20C org. residues (2 of the valences opt. forming a double bond) or of (b) mono-, di- or tribasic org. or inorg. fully amidated acids of tri- or pentavalent phosphorus, the N-atoms of which are alkylated with is not >20C aliphatic residues and the organic residues of which contain is not >20C-atoms, opt. in the presence of an inert solvent. |
