| abstract | 1366379 N-phosphonomethyl glycine and derivatives thereof MONSANTO CO 22 Oct 1971 [10 March 1971 9 Aug 1971] 49263/71 Heading C2P [Also in Division A5] Compounds of Formula I where R, R<SP>1</SP> and R<SP>2</SP> are each -OH; -NR<SP>4</SP>R<SP>5</SP> where R<SP>4</SP> and R<SP>5</SP> are each H, C 1-4 alkyl or hydroxyalkyl or C 2-4 alkenyl or R<SP>4</SP> and R<SP>5</SP> together with N form a heterocyclic ring; -OR<SP>3</SP> where R<SP>3</SP> is C 1-18 hydrocarbyl or hydrocarbyloxyhydrocarbyl optionally substituted by 1 to 3 halogen atoms, the hydrocarbyloxyhydrocarbyl groups also being optionally substituted by one or more hydrocarbyloxy groups, or a -C n H 2n -NR<SP>4</SP>R<SP>5</SP> group where n is 1 to 4; or -OR<SP>6</SP> where R<SP>6</SP> is alkali metal, alkaline earth metal, Cu, Zn, Mn, Ni, ammonium or organic ammonium, provided (i) that no more than 2 of R, R<SP>1</SP> and R<SP>2</SP> are selected from -NR<SP>4</SP>R<SP>5</SP> and -OR<SP>3</SP>, (ii) that when R<SP>6</SP> is arylammonium it is the cation of a primary amine, (iii) that no more than 2 of R, R<SP>1</SP> and R<SP>2</SP> are -OR<SP>6</SP> when R<SP>6</SP> is ammonium or organic ammonium, and (iv) that no more than 2 of R, R<SP>1</SP> and R<SP>2</SP> are -OH; and salts of the compound of Formula I in which R, R<SP>1</SP> and R<SP>2</SP> are each -OH with an acid having a pK of 2À5 or less are claimed per se. Compounds of Formula I, including the compound in which each of R, R<SP>1</SP> and R<SP>2</SP> is -OH (N-phosphonomethyl glycine), which compounds may be used as the active ingredients in conventional pesticidal compositions, may be prepared by phosphonomethylation of a glycine, by phosphite addition to azomethines or by oxidation of the corresponding phosphinic compounds. The amides and esters may also be prepared by reacting the corresponding acid halide or the methyl ester with the corresponding amine or alcohol. The salts may be prepared by partial or complete neutralization with the appropriate base. |
