A cobalt coordination polymer from bulk to nanoscale crystals as heterogeneous catalysts for tandem reactions

Constructing nanoscale coordination polymers (CPs) with different micro- or nanoscale morphologies and sizes is crucial for the functionalization of CPs-based heterogeneous catalysts. Herein, surfactant polyvinylpyrrolidone (PVP), surface-supported frameworks (filter paper or Ni foam), and Co-based CPs (1), [Co2(pdpa)(py)4(H2O)]n (H4pdpa ?= ?5,5’-(pentane-1,2-diyl)-bis(oxy)diisophthalic; py ?= ?pyridine)) were employed to develop highly ordered micro- or nanoscale CPs, achieving microscale 1a (without surface-supported framework) and nanoscale 1b-c (filter paper and Ni foam as surface-supported frameworks for 1b and 1c, respectively). Furthermore, the catalytic performance of nanoscale 1c with spheric particles for the tandem conversion reactions of aromatic nitriles and diamines into imidazoline or tetrahydropyrimidine frameworks was much more prominent than that of large scale 1, microscale 1a, and nanoscale 1b because of the easily accessible catalytic active sites in the nanoscale spheric particles, which offered a functionalizable platform for the tandem reactions by minimizing the diffusion distance but did little for their activity.

1, 4, 5, 6-tetrahydro-pyrimidine derivative synthesis method

The invention discloses a novel method for synthesizing a 1,4,5,6-tetrahydropyrimidine derivative. The derivative is prepared through reaction between 2-aryl-substituted nitrile and 1,3-diaminopropane with copper cinnamate as a catalyst. The novel method has the advantages that the synthesis technology is simple and does not have strict requirements on reaction conditions, and the catalyst is cheap and can be reutilized, thereby facilitating actual production; the yield can reach 60%-90%.
