Abstract: 2,3-Dihydro-5,6-diphenyl-1,4-oxathiin is prepared by reacting benzoin and 2-mercaptoethanol in an alkanol solvent of 2 to 8 carbon atoms and an acidic catalyst. The use of alcohol solvent in lieu of aromatic solvents gives much greater purity with much better yields.

Abstract: Substituted 2,3-dihydro-1,4-oxathiins of the formula ##STR1## display useful plant growth regulant effects including herbicidal effects. Examples are 2,3-dihydro-5,6-diphenyl-1,4-oxathiin, and 2,3-dihydro-5-(4-methylphenyl)-6-phenyl-1,4-oxathiin 4-oxide. The compounds are useful for the selective control of grasses and as dwarfing agents, as well as for inhibition of vegetative and reproductive axillary growth, and for increasing the sugar content of sugar producing species. A number of these are new compounds.

Abstract: A broad class of furan-3-Carboxamide derivatives, including many novel compounds, can be made reliably and in good yields by a novel one step reaction between an .alpha.-hydroxyketone and an acetamide in the presence of a Friedel-Crafts agent in an inert solvent. The broad class of derivatives has fungicidal and insecticidal utility.

Abstract: Substituted 2,3-dihydro-1,4-oxathiins of the formula ##SPC1##Display useful plant growth regulant effects including herbicidal effects. Examples are 2,3-dihydro-5,6-diphenyl-1,4-oxathiin, and 2,3-dihydro-5-(4-methyl-phenyl)-6-phenyl-1,4-oxathiin 4-oxide. The compounds are useful for the selective control of grasses and as dwarfing agents, as well as for inhibition of vegetative and reproductive axillary growth, and for increasing the sugar content of sugar producing species. A number of these are new compounds.This invention relates to a method of regulating the growth of plants and to plant growth regulant compositions useful in such method, as well as to chemical compounds useful in such compositions.Regulation of the growth of plants is frequently desirable for a number of reasons. For example, the control of weeds is of great economic importance. Weed competition inhibits the production of foliage, fruit or seed of agricultural crops.
