  Synthesis of Water-Soluble, Aliphatic Phosphines and Their Application to Well-Defined Ruthenium Olefin Metathesis Catalysts

  摘要：

  Water-soluble aliphatic phosphines Cy(2)P(CH2)(2)N(CH3)(3)Cl-+(-) (14), Cy(2)P[4-(N,N-dimethyl-piperidinium)]Cl-+(-) (15), Cy(2)P(CH2)(2)SO3-Na+ (16), and CyP[(CH2)(2)N(CH3)(3)Cl-+(-)](2) (17) (Cy = cyclohexyl) were prepared from air-stable, borane-protected precursors. Spectroscopic investigations of corresponding Pd(PR(3))(2)Cl-2 complexes were used to estimate the steric parameters of these new phosphines. Spectroscopic investigation of Ni(CO)(3)PR(3) complexes of the new phosphines indicated that phosphines bearing quaternary amine functionalities were less electron donating than tricyclohexylphosphine, while the presence of a sulfonate group increased phosphine electron donation. Cationic phosphines 14 and 15 were used to synthesize water-soluble ruthenium carbene complexes of the type (Cy(2)PR)(2)Cl2Ru=CHPh. These complexes initiate the ring-opening metathesis polymerization (ROMP) of functionalized 7-oxanorbornenes in water, methanol, and aqueous emulsions.

  使用三配位铁（II）β-二酮亚胺预催化剂进行膦和胺-硼烷的脱氢偶联反应

  摘要：

  据报道，使用β-二金属铁（II）与膦和胺-硼烷进行脱氢偶联。胺-硼烷的脱氢偶联比膦类相对容易得多，前者在室温下用1摩尔％的铁预催化剂进行。这种低负荷足以进行原位动力学分析和氘标记研究。还已分离出酰胺基-硼烷铁络合物，据信这是催化剂的静止状态。总体而言，这使我们能够提出催化循环，该循环通过释放二硼氮烷，氢化铁和酰胺基硼烷铁中间体而进行。

  bi‐dimensional NMR analyses, indicates a strong influence of the phosphorus substituent on the structure of the gem‐dianionic phosphorus structure; a monomeric arrangement was obtained when R=phenyl, whereas a cyclic oligomer was observed for R=cyclohexyl. These compounds represent a new type of useful reagent, and their access paves the way for the concept of “RP synthons” (i.e., RP2− phosphandiides), likely

  from the formation of the parallel product resulting from P–B bond cleavage. H3B·PCyH2 undergoes a similar dehydrocoupling process, and gives a mixture of stereoisomers of the resulting metal-bound diboraphosphine that arise from activation of the prochiral P–H bonds, with one stereoisomer favored. This diastereomeric mixture may also be biased by use of a chiral phosphine ligand. The selectivity and efficiencies
