    摘要: This disclosure relates to a class of alpha-chloro-N-alkoxymethyl-N-(2,6-dialkoxyphenyl)acetamides which are effective in regulating the natural growth or development of plants. As employed herein, the term "natural growth or development" designates the normal life cycle of the plant in accordance with its genetics and its environment, in the absence of artificial, external influences. More particularly, this disclosure is concerned with a method wherein turfgrasses are treated with an alpha-chloro-N-alkoxymethyl-N-(2,6-dialkoxyphenyl)acetamide which serves to retard or reduce the rate of turfgrass growth. Such a treatment may also serve to retard or reduce the formation of seedheads and seedhead stalk elongation.

    摘要: The present invention is directed to a process for the preparation of certain N-substituted-2-haloacetanilides via the reaction of a secondary 2-haloacetanilide with a haloalkyl ether, particularly, halomethyl ethers, which comprises forming the ether in situ by the in-solvent reaction of an alcohol, formaldehyde or other aldehyde and an acid halide to produce high purity haloalkyl ethers, while decreasing the concentration of undesirable bis by products, as for example bis(chloromethyl) ether. The ether formed in situ thereafter reacts with the secondary 2-haloacetanilide in the presence of a phase transfer catalyst and base to form the N-substituted-2-haloacetanilide.

    摘要: This invention relates to a process for the preparation of 2-(methylthiomethyl)-6-(trifluoromethyl) aniline, [MTA], from ortho-aminobenzotrifluoride, (OABT), employing a single solvent transformation via a sulfilimine intermediate. A sulfilimine hydrochloride salt is prepared by the oxidative addition of dimethyl sulfide to OABT in the presence of N-chlorosuccinimide. Neutralization of the sulfilimine hydrochloride salt with aqueous sodium hydroxide followed by phase separation results in an organic phase containing free sulfilimine and an aqueous phase generally containing succinimide and/or sodium succinimide. In a preferred embodiment the phase separation is performed in such a manner to leave a catalytic amount of succinimide in the organic phase. The free sulfilimine catalytically rearranges at moderate temperatures in the presence of this succinimide catalyst to form MTA. The aqueous phase separated after neutralization of the sulfilimine hydrochloride salt contains succinimide and/or sodium succinimide which may be converted by the action of chlorine to N-chlorosuccinimide which in turn may be recycled to the first step in the process.

    化物氧化加成到OABT中来制备盐酸亚硫酰胺盐。 将亚硫酰胺盐酸盐与氢氧化钠水溶液中和,随后进行相分离,得到含有游离的亚硫酰亚胺和通常含有琥珀酰亚胺和/或琥珀酰亚胺钠的水相的有机相。 在优选的实施方案中,相分离以这样一种方式进行,即在有机相中留下催化量的琥珀酰亚胺。 在该琥珀酰亚胺催化剂的存在下,游离的亚硫酰亚胺在中等温度下催化重排以形成MTA。 在中和硫酸亚胺盐酸盐后分离的水相含有琥珀酰亚胺和/或琥珀酰亚胺钠,其可以通过氯的作用转化为N-氯代琥珀酰亚胺,而N-氯代琥珀酰亚胺又可以再循环到该方法的第一步。
