  Abstract A ruthenium based catalytic system ([Ru(p-cymene)Cl2]2/XantPhos with substoichiometric Cs2CO3) has been established to effectively achieve the first direct amination cyclization of 1,2,4-butanetriol with primary aromatic amines. The product of this sustainable hydrogen autotransfer process is valuable N-aryl-3-pyrrolidinol.

  摘要建立了钌基催化体系（[Ru（p-cymene）Cl2] 2 / XantPhos和亚化学计量的Cs2CO3），以有效地实现1,2,4-丁三醇与伯芳族胺的首次直接胺化环化。这种可持续的氢自动转移过程的产物是有价值的N-芳基-3-吡咯烷醇。

• PROCESS FOR TREATING KERATIN FIBRES WITH A PHOTOCROSSLINKABLE POLYVINYL ALCOHOL
  申请人：L'OREAL

  公开号：US20190343754A1

  公开（公告）日：2019-11-14

  The invention relates to a cosmetic process for treating keratin fibres, comprising: (i) a step of applying to the keratin fibres a cosmetic composition containing a polyvinyl alcohol polymer comprising:—an alcohol unit—optionally an acetate unit—a photocrosslinkable unit—a hydrophobic unit; (ii) a step of irradiating the composition on the keratin fibres to crosslink said polymer. The invention also relates to the novel polyvinyl alcohol polymer used in said process. The treated keratin fibres have good cosmetic properties in terms of a soft feel and disentangling, which properties are persistent after one or more shampoo washes.
