含金属盐和中性有机碱的杂化催化剂分子内烯烃加氢胺化

摘要：

由碱土金属碘化物（AeI 2）和Schwesinger碱t Bu P4组成的杂化催化剂催化H 2 C = CHCH 2 CR 2 CH 2 NH 2 [CR 2 = CPh 2，C（CH 2）5， CMe 2 ]。活性沿行减少：Ca> Sr >> Mg> Ba。发现由t Bu P4和ZnI 2，AlI 3，FeCl 3或NaI组成的杂化催化剂是完全惰性的。另外，杂化催化剂t BuP3 / CaI 2没有活性，这意味着非亲核有机碱的碱基强度必须高于t Bu P3的碱基强度（p K a BH + = 38.6）。发现t Bu P4与CaX 2（X = Cl，Br，O i Pr，OTf，NTf 2）的组合是完全无活性的，这部分可以由溶解性差解释。因此，混合催化方法仅限于t Bu P4 / CaI 2的组合但是碘化物配体可以被手性配体部分或完全代替。杂化催化剂的手性改性使分子内烯烃加氢胺ee值高达33％。

Stabilization of Ketone and Aldehyde Enols by Formation of Hydrogen Bonds to Phosphazene Enolates and Their Aldol Products

作者：Kristopher J. Kolonko、Hans J. Reich

the benzyl ketones 1a and 1b, the acetophenone 2, the arylacetaldehyde 1c, and the methyl arylacetate 1d formed the expected "naked" (P4H+) enolates 3 and 7. However, at a half-equivalent of base the ketones 1a and 1b as well as the aldehyde 1c formed solutions of stable hydrogen-bonded dimeric (enol-enolate) structures (4). The acetophenone 2, on the other hand, forms only traces of the H-bonded dimer
