摘要:研发了许多取代的α,β-不饱和环己烯酮和环己烯醇的硼氢化.酮和伪赤道醇以适度收率产生了二赤道反式-1,2-二醇,并伴有少量的1,3-二醇.已经确定了中间烯丙基硼酸酯的指导作用和环取代基对该反应的空间影响.1,3-环己二酮的氢硼化已显示出主要通过加成消除过程进行,从而反应生成二季基反式-1,2-环己二醇,从而将1,3-二氧代环己烷转化为1,2-二氧代环己烷,1,2-环己二酮在硼氢化处理中主要给予顺式-1,2-环己二醇.提出了1,2和1,3-环己二酮氢硼化的机理,两者都在一定程度上涉及氢在氢硼酸或硼烷中的异常分子内置换并保留了构型.

摘要:A method of synthesizing polyamide microparticles may comprise: dehydrating and shearing a mixture comprising a matrix fluid, an emulsion stabilizer at about 0.01 wt % to about 50 wt % based on the weight of the matrix fluid, a solvent at about 13 wt % to about 75 wt % based on the weight of the matrix fluid, and a cyclic amide monomer at about 20 wt % to about 90 wt % based on the weight of the matrix fluid to yield an emulsion having a water content of about 1 wt % or less based on the total weight of the emulsion; adding a deprotonating agent to the emulsion at a concentration of about 0.01 wt % to about 1 wt % based on the weight of the matrix fluid; and contacting the emulsion with a polymerization initiator under conditions effective to polymerize the cyclic amide monomer into a plurality of polyamide microparticles.
