Trawny, Daniel published the artcileModular syntheses of star-shaped pyridine, bipyridine, and terpyridine derivatives by employing Sonogashira reactions, Application of Ethyl 6-chloropicolinate, the main research area is pyridine preparation; trialkyne pyridine Sonogashira reaction; bipyridine preparation; bromo bipyridine trialkyne Sonogashira reaction; terpyridine preparation; nonaflate terpyridine trialkyne Sonogashira reaction.
A simple and flexible synthesis for a series C3-sym. core units of star-shaped pyridine e.g., I, bipyridine e.g., II and terpyridine derivatives e.g., III by employing a Sonogashira reaction in the crucial final step was described. A star-shaped dodecafluorinated compound I was also prepared in a straightforward fashion. A simple procedure for the preparation of partially silylated 1,3,5-triethynylbenzene derivatives was presented, which provides an approach to C2-sym. star-shaped compounds that have only one terpyridine and two terphenyl units as ‘dummy’ ligands. The absorption and emission spectra of the fully conjugated C3-sym. pyridine derivatives were systematically investigated, and fairly large Stokes shifts were observed
