制备方法与用途

异丁胺盐酸盐是一种有机胺盐酸盐，据文献报道，它可以用于制备3-(2-氨基-2-硫代乙基)苯甲酸甲酯。这种化合物是重要的精细化工原料和医药中间体，并且是合成新型磷酸盐运输抑制剂2-[[3-[[4-(2-羟乙基)-2-噻唑基]甲基]苯甲酰基]氨基]-5-(1-哌啶基)-(2E)-2-[[4-氯-3-(三氟甲基)苯基]亚甲基]苯甲酰肼的关键中间体。

  Catalytic Double-Bond Metathesis without the Transition Metal

  摘要：

  Iminophosphoranes of the type X3P=NR (X=Cl, pyrrolyl; R=alkyl, aryl) catalytically metathesize C=N bonds of carbodiimides via an addition/elimination mechanism that, despite the lack of d orbital participation in P-N bonding, conserves the key features of metal-catalyzed olefin metathesis. Diazaphosphetidine intermediates, produced by the formal [2+2] addition of carbodiimides to the P=N bond, have been isolated and characterized. All phosphorus-containing species in the complex catalytic reaction mixtures have been identified and their origins explained. The kinetics of addition of diisopropylcarbodiimide to Cl3P=NPl and subsequent elimination were studied, and rate constants were determined: k(add)=1.7x10(-3) (+/-0.1x10(-3)) M s(-1) and k(elim)=4.0x10(-4) (+/-0.3x10(-4)) s(-1). The rate of these reactions corresponds well with the observed catalytic TOF of 1.44 TO/P/h.

  Transition metal catalysis that utilizes N-heterocyclic carbenes as noninnocent ligands in promoting transformations has not been well studied. We report here a cyclic (alkyl)(amino)carbene (CAAC) ligand-promoted nitro deoxygenative hydroboration with cost-effective chromium catalysis. Using 1 mol % of CAAC-Cr precatalyst, the addition of HBpin to nitro scaffolds leads to deoxygenation, allowing for
