• Synthesis of Cp*CH2PPh2 and its use as a ligand for the nickel-catalysed cross-coupling reaction of alkyl halides with aryl Grignard reagents

  A new ligand, Cp*CH2PPh2 (Cp* = 1,2,3,4,5-pentamethyl-2,4-cyclopentadienyl), was prepared, and was used as a ligand for nickel-catalysed cross-coupling reaction of alkyl halides with aryl Grignard reagents, which nickel-phosphine complexes had never made possible.

  Asymmetrically substituted tertiary phosphines and quaternary phosphonium salts are used extensively in applications throughout industry and academia. Despite their significance, classical methods to synthesize such compounds often demand either harsh reaction conditions, prefunctionalization of starting materials, highly sensitive organometallic reagents, or expensive transition‐metal catalysts.

  不对称取代的叔膦和季鏻盐广泛应用于工业界和学术界。尽管它们很重要，但合成此类化合物的经典方法通常需要苛刻的反应条件、起始材料的预官能化、高度敏感的有机金属试剂或昂贵的过渡金属催化剂。因此，尽管目前人们很感兴趣，但温和、实用的方法仍然难以捉摸。在这里，我们描述了一种可见光驱动的方法，由仲膦和伯膦形成这些产品。使用廉价的有机光催化剂和蓝光照射，芳基膦可以使用市售的有机卤化物进行烷基化和芳基化。此外，相同的有机催化剂可用于在单个反应步骤中将白磷（P 4 ）直接转化为对称芳基膦和鏻盐，这在以前只能使用贵金属催化来实现。

  used ligands, catalysts, and reagents. Current synthetic approaches to phosphines are dominated by nucleophilic displacement reactions with organometallic reagents. Here, we report a radical-based approach to phosphines that proceeds by a cross-electrophile coupling of chlorophosphines and redox-active esters. The reaction allows for the synthesis of a broad range of substituted phosphines that were not

Disubstituted derivatives (IIIa) containing PR3(R = Et, OMe)ligands were also made from Ia.

  Compositions of matter are disclosed which are highly useful in hydroformylation processes. The compositions are non-charged, non-chelated bis- and tris-(alkyl diaryl phosphine) rhodium carbonyl hydrides. The substituents of the alkyl group includes heteroorganic radicals containing ether, ester, keto and hydroxy oxygen, phosphine oxide and phosphorus ester phosphorus, amine, amide, amine oxide and heterocyclic nitrogen groups. These compositions are highly stable and selective catalysts for the hydroformylation of olefins under certain conditions. The disclosed catalyst systems contain a large excess of phosphine ligand and employ alpha-olefin plus synthesis gas reactant mixtures having a high H.sub.2 /CO ratio at relatively low pressures. They produce moslty aldehydes derived from terminal attack on the alpha-olefin reactant. In the case of low olefins, such as butene-1, the products can be advantageously removed in a continuous manner, as distillate components from a ligand reaction mixture kept at an elevated temperature and continuously fed by an appropriate mixture of the reactants.

  本发明披露了一种在氢甲酰化过程中非常有用的物质组成物。该组成物是非带电、非螯合的双(烷基二芳基膦)、三(烷基二芳基膦)铑羰基氢化物。烷基基团的取代基包括含有醚、酯、酮和羟基氧、膦氧和磷酸酯磷、胺、酰胺、胺氧和杂环氮基的杂有机基团。这些组成物是高度稳定和选择性的催化剂，可在一定条件下用于烯烃的氢甲酰化反应。披露的催化剂体系含有大量的膦配体，并采用具有高H.sub.2/CO比的α-烯烃加合物和合成气反应物混合物，在相对较低的压力下。它们主要产生从α-烯烃反应物的末端攻击中得到的醛。对于低烯烃，例如丁烯-1，可以从保持在高温下并由适当的反应物混合物连续供给的配体反应混合物中以馏分组分的形式优势地去除产物。
