Methylformate as replacement of syngas in one-pot catalytic synthesis of amines from olefins
general approach for the one-pot hydroaminomethylation of olefinsusing methylformate as formylating agent instead of synthesis gas (syngas) has been proposed. Herein we report that a Ru–Rh catalytic system demonstrates high activity in a tandem conversion of a series of n-alkenes into aminesusing methylformate with yields 58–92% (6 h). The selectivity for the normal amine reached 96% with catalysis by

hydroformylation of linear terminal alkenes using rhodium based catalysts under fluorous biphasic conditions in the presence and absence of toluene is reported. Using fluorinated ponytails to modify triarylphosphites and triarylphosphines, good selectivities and reactivities can be obtained, along with good retention of the catalyst and ligand within the fluorous phase. Using P(O–4-C6H4C6F13)3 (P/Rh=3:1) as the
据报道,在氟的双相条件下,在存在和不存在甲苯的情况下,使用铑基催化剂将线性末端烯烃加氢甲酰化。使用氟化的马尾辫来修饰亚磷酸三芳基酯和亚磷酸三芳基酯,可以获得很好的选择性和反应性,以及催化剂和配体在氟相中的良好保留。使用P(O–4-C 6 H 4 C 6 F 13)3(P / Rh = 3∶1)作为甲苯/全氟-1,3-二甲基环己烷中的配体,在60℃下获得了良好的结果,但是随着温度的升高,催化剂和/或配体发生分解。通过以更高的速率,更好的l / b比以及以全氟化碳溶剂形式更好地保留催化剂和亚磷酸酯而省略甲苯,可以获得更令人印象深刻的结果。竞争性异构化将线性醛的选择性限制在<76%。当P(4-C 6 H 4 C 6 F 13)3在没有甲苯的情况下将其用作配体,甚至可以获得更令人印象深刻的结果,线性醛的选择性高达80.9%,高速率,保留率高达99.95%的铑和高达96.7%的膦在氟相中。将这些结果

We report the formation of high-precision catalysts using encapsulated rhodium complexes. In the current example, the encapsulated rhodium catalyst shows unprecedented high selectivity in the rhodium-catalyzed hydroformylation of internal alkenes, forming predominantly one of the branched aldehydes. This catalyst system is the first example that is able to discriminate between carbon atoms C3 and C4
