| titleOfInvention | PROCEDURE FOR OBTAINING SUBSTITUTE DIOXANS WITH HERBICIDAL EFFECT. |
| abstract | Procedure for obtaining herbicidal-effect substituted dioxanes of general formula: **(See formula)** where R is hydrogen, alkyl, haloalkyl, cyanoalkyl, aryl, aryloxyalkyl, arylalkoxyalkyl or alkoxyalkyl, where any alkyl or substituted alkyl radical contains from 1 to 6 carbon atoms and any aryl radical is unsubstituted phenyl, furyl or thienyl or bearing a single X substituent defined as F, Cl, Br, lower alkyl, lower alkoxy, or benzyloxy; R2a is hydrogen or methyl and R2a and R2a together can represent two or more methylenes groups and thus form a spiral structure; R5 is hydrogen, alkyl, chloroalkyl or bromoalkyl, said alkyl groups containing from 1 to 4 carbon atoms; Rr is a phenyl, furyl, thienyl or monovalent aromatic pyridyl unsubstituted or having one, two or three Y substituents, defined as F, Cl, Br, CN, CF3, lower alkyl, or lower alkoxy, assuming that when Rr where unsubstituted phenyl and R2a is hydrogen and R5 is hydrogen or methyl, then R2 is a radical other than unsubstituted phenyl; characterized by: (a) either (1) substituted 5-hydroxy-1,3-dioxane, **(See formula)** in a solvent with sodium hydride to form the corresponding sodium alcoholate which is then reacted with arylmethyl chloride or bromide, Rr-CH2-Cl or Rr-CH2-Br, or (2) 2-arylmethoxy-1,3 is reacted -propanediol, Rr-CH2-O-OH (CH2OH) 2 with a carbonyl compound, R2 R2a C = O, in the presence of an acid catalyst; and (b) the product is separated from the reaction mixture.
