    • The fungicidal compound 4,5-dimethyl-N-2-propenyl-2-(trimethylsilyl)-3-thiophenecarboxamide (Formula (I) shown superior and unexpected control of the growth of the soil-borne fungus Gaeumannomyces graminis (Gg). The present invention provides a novel compound for synthesizing the compound of Formula (I) which uses the compound 4-hydroxy-4,5-dimethyl-2-trimethylsilanyl-dihydrothiophene-3-carboxylic acid allylamide (Formula (II)) as well as novel compounds of synthesizing the allylamide. In addition, Formula (II) itself has unexpectedly been found to provide control of Gg. Therefore, the compounds having Formula (III): ##STR1## or an agronomic salts and compositions thereof are expected to provide such control as well; wherein:Q is --NH, S, or O;W is O, or S;X is --OH, --OAc, --OR, where R is lower alkyl;Y is S, O, or --NH;Z is --Si(R).sub.3, --C(R).sub.3, where R is lower alkyl;R.sub.1 is a lower alkyl, allyl, or propargyl;R.sub.2 is a lower alkyl or aryl; andR.sub.3 and R.sub.4 are independently chosen from hydrogen, a lower alkyl and aryl;optionally, R.sub.2 and R.sub.3 together form a 5- or 6-membered ring.

    • A process for the production of N-(phosphonomethyl)iminodiacetic acid. N-(acetyl)iminodiacetic acid is formed in a amidocarboxymethylation reactor system, into which a source of each of the following is continuously fed: (1) acetamide or an acetamide derivative, (2) formaldehyde or a formaldehyde generator or derivative, (3) a carbonylation catalyst, (4) carbon monoxide, and optionally (5) hydrogen. In turn, an amidocarboxymethylation reaction product stream, which contains N-(acetyl)iminodiacetic acid and the carbonylation catalyst, is withdrawn from the amidocarboxymethylation reactor system. The carbonylation catalyst is separated from the amidocarboxymethylation reaction product stream to recover the carbonylation catalyst and form a catalyst depleted product stream which contains N-(acetyl)iminodiacetic acid. The separated carbonylation catalyst is returned to the amidocarboxymethylation reactor system, and the N-(acetyl)iminodiacetic acid in the catalyst depleted product stream is either: (1) reacted with a source of phosphorous and a source of formaldehyde in the presence of an acid to form a phosphonomethylation reaction product stream containing N-(phosphonomethyl)iminodiacetic acid and acetic acid; or (2) deacylated and cyclized to form a 2,5-diketopiperazine, and then reacted with a source of phosphorous and a source of formaldehyde in the presence of an acid to form a phosphonomethylation reaction product stream containing N-(phosphonomethyl)iminodiacetic acid and acetic acid. Either way, the N-(phosphonomethyl)iminodiacetic acid is precipitated from the phosphonomethylation reaction product stream in the presence of acetic acid, and the precipitate is recovered to form a filtrate stream.
