Novel 1-oxa-4-azonium cyclohexane salts are described. These compounds can be used as structure directing agents, and they overcome many of the typical problems associated with OSDA synthesis and subsequent zeolite synthesis. Methods for synthesis of the 1-oxa-4-azonium cyclohexane salts from a variety of starting materials are also described.
A substituted hydrocarbon is added to water to form a mixture, and a 1-oxa-4-azacyclohexane derivative is then added. The reaction mixture stirred until a solution containing the 1-oxa-4-azonium cyclohexane salt is obtained.

A process for preparing glyphosate and derivatives of related structure. A precursor primary or secondary amine, such as glycine, is condensed with a carbonyl compound, such as formylphosphonic acid or its acetais, and the condensation product is reduced to produce the desired product.

A process for preparing glyphosate and other secondary or tertiary amines of related structure in which a precursor primary or secondary amine, such as aminomethylphosphonic acid, is condensed with glyoxylic acid, glyoxal, or a related carbonyl compound, and the condensation product is reduced without isolation to produce the desired product.
