  high catalytic activity in the ring‐opening polymerization of ε‐caprolactone and enable quantitative conversion of 500 equiv. of monomer in 5 seconds (22 °C). Polymerization of rac‐lactide initiated by 1 and 2 proceeds much slower: 52–72 % conversion ([M]0/[Ca]0 = 100) was reached in 12 h (20 °C). The obtained polymers are characterized by narrow polydispersities (Mw/Mn = 1.22–1.28). Catalytic activity

  Methods have been developed to produce phosphazene modified organic or siloxane polymers. The method includes (a) providing an organic or siloxane polymer comprising phosphine units, and (b) reacting the organic or siloxane polymer with a phosphazene azide compound under conditions wherein the phosphazene azide compound is bound to the phosphine units in the polymer, thereby producing the phosphazene-modified organic or siloxane polymer. The organic polymer of step (a) is produced by reacting a first monomer comprising phosphine with a second monomer via free radical or anionic polymerization techniques to produce the organic polymer comprising phosphine units. The first and second monomers can be identical. A wide variety of organic polymer backbones can be modified using these techniques. The second monomer, for example, can be selected from monomers forming polyolefins, polydienes, polyacrylics, polyethylenes, polyvinyl chlorides, polyisoprenes, polystyrenes, polycaprolactam, poly(methyl)(meth)acrylates, and polypropylenes. Alternatively, the siloxane polymer of step (a) is produced by reacting a monomer comprising phosphine with a hydrosilicone polymer via hydrosilylation polymerization techniques to produce the siloxane polymer comprising phosphine units. These phosphazene modified organic and siloxane polymers are useful in a variety of applications, particularly as a fire retardant material.

  已开发出生产叠氮化磷改性有机聚合物或硅氧烷聚合物的方法。该方法包括：(a) 提供包含膦单元的有机聚合物或硅氧烷聚合物；(b) 在叠氮化磷化合物与聚合物中的膦单元结合的条件下，使有机聚合物或硅氧烷聚合物与叠氮化磷化合物反应，从而制得叠氮化磷改性有机聚合物或硅氧烷聚合物。步骤(a)中的有机聚合物是通过自由基或阴离子聚合技术使包含膦的第一单体与第二单体反应，生成包含膦单元的有机聚合物。第一和第二单体可以是相同的。可以使用这些技术对多种有机聚合物骨架进行改性。例如，第二单体可以选自形成聚烯烃、聚二烯、聚丙烯酸、聚乙烯、聚氯乙烯、聚异戊二烯、聚苯乙烯、聚己内酰胺、聚甲基丙烯酸酯和聚丙烯酸酯的单体。另外，步骤(a)中的硅氧烷聚合物是通过氢化硅聚合技术，使含磷单体与氢硅氧烷聚合物反应，生成含磷单元的硅氧烷聚合物。这些膦苯改性有机聚合物和硅氧烷聚合物可用于多种用途，特别是用作阻燃材料。

  The phosphine substrate scope in dehydrocoupling reactions catalyzed by Cp-2*SnCl2 (Cp* = pentamethylcyclopentadienyl, 1) have been explored. Catalyst variants R2SnX2 (R = Cp*, Ph; X = Cl, Me, Ph) were also tested, which revealed that activity is dependent on the Cp* ligands as well as more electron withdrawing X ligands. Steric factors at the phosphine substrate are also important. Compound 1 was found to be a catalyst for hydrophosphination of styrene, 2,3-dimethylbutadiene, and diphenylacetylene with phenylphosphine, which is the first example of a p-block catalyst for hydrophosphination.
