  Processes for making an organozinc reagents are disclosed comprising reacting (A) organomagnesium or organozinc complexes with (B) at least one coordination compound comprising one or more carboxylate groups and/or alcoholate groups and/or tertiary amine groups, optionally in combination with zinc ions and/or lithium ions and/or halide ions, wherein the halide ions are selected from chloride, bromide and iodide, the organozinc complex comprises an aryl group, a heteroaryl group or a benzyl group when the coordinating compound is a chelating polyamine, and the reaction is conducted in the presence of zinc complexed with at least one coordinating compound when reactant (A) comprises at least one organomagnesium complex. The resulting organozinc reagents may optionally be isolated from solvents to obtain a solid reagent. The reagents may be used for making organic compounds via Negishi cross-coupling reactions or via aldehyde and/or ketone oxidative addition reactions. The organozinc reagents are stable and, due to their high selectivity, permit maintenance of sensitive functional groups such as aldehydes during cross-coupling.

  公开了制备有机锌试剂的方法，包括将（A）有机镁或有机锌配合物与（B）至少一种含有一个或多个羧酸基团和/或醇基团和/或三级胺基团的配位化合物反应，可选地与锌离子和/或锂离子和/或卤离子结合，其中卤离子选自氯离子、溴离子和碘离子，当配位化合物为螯合多胺时，有机锌配合物包括芳基、杂环芳基或苄基，当反应物（A）包含至少一种有机镁配合物时，在存在至少一种配位化合物与锌络合物的情况下进行反应。所得的有机锌试剂可以选择性地从溶剂中分离出来以获得固体试剂。这些试剂可用于通过Negishi交叉偶联反应或通过醛和/或酮氧化加成反应制备有机化合物。有机锌试剂稳定，并且由于其高选择性，允许在交叉偶联过程中保持敏感的官能团，如醛基。

  Alkylene oxide polymerizations are performed in the presence of a double metal cyanide polymerization catalyst and certain magnesium, Group 3-Group 15 metal or lanthanide series metal compounds. The presence of the magnesium, Group 3-Group 15 metal or lanthanide series metal compound provides several benefits including more rapid catalyst activation, faster polymerization rates and the reduction in the amount of ultra high molecular weight polymers that are formed. The catalyst mixture is unexpectedly useful in making polyethers having low equivalent weights.

  在双金属氰化物聚合催化剂和某些镁、3-15族金属或镧系金属化合物的存在下进行烯丙基氧化物聚合反应。镁、3-15族金属或镧系金属化合物的存在提供了多种好处，包括更快的催化剂活化、更快的聚合速率以及减少形成超高分子量聚合物的数量。这种催化剂混合物在制备低当量重聚醚时具有意外的有用性。

  The molecular weight of polyalkylene oxides produced by the polymerization of a cyclic oxide in contact with a catalyst comprising the reaction product of a dihydrocarbyl zinc compound and a linear alkanediol in contact with a silica dispersion aid and nonionic surfactant in an inert diluent is controlled by the continuous addition of a very dilute solution of chain transfer agent having a pKa value of from 9 to 22 to the polymerizing mixture during the polymerization reaction at a carefully controlled rate so as not to terminate the polymerization reaction.
