Reaction of 1,2- and 1,6-dihydro-3-ethyl-N-methyl pyridine tricarbonylchromium(0) complexes with methyllithium at low temperature afforded a high yield of dimeric tricarbonylchromium(0) complexes. Structures of the latter products were established by X-ray crystallographic analysis. Some chemistry of these novel compounds is described.

Disclosed is a method for preparing 2,2′-dipyridine and derivatives thereof. The method includes: using pyridine represented by formula I or a derivative thereof as a raw material to generate 2,2′-dipyridine represented by formula II by performing dehydrogenative coupling under the action of a supported catalyst in the presence of additives, where R is H, C1-C2 alkyl, Cl, or Br. The method of the present invention features wide adaptability to raw materials, high atomic utilization rate, high catalyst activity, long service life, and fewer by-products.

approach was developed for the synthesis of the well-known BlueCage by pre-bridging two 2,4,6-tris(4-pyridyl)-1,3,5-triazine (TPT) panels with one linker followed by cage formation in a much improved yield and shortened reaction time. Such a stepwise methodology was further applied to synthesize three new pyridinium organic cages, C2, C3, and C4, where the low-symmetry cages C3 and C4 with angled panels
