Abstract

Synthesis and NMR spectral studies of multidentate N and S heterocycles, 1,3,5‐tris(N‐methylbenzimidazolyl)benzene, 1,3,5‐tris(benzimidazolyl)benzene,1,3,5‐tris(benzothiazolyl) benzene, 2,2′‐bipyridine 3,3′‐bis(benzothiazolyl)benzene and 1,2,4,5‐tetrakis(benzothiazolyl) benzene have been carried out. 2D ^1^H^1^H PFG‐COSY as well as ^1^H^13^C single and multiple bond correlated (2D GRASP‐HSQC and GRASP‐HMBC) experiments have been employed to characterize the compounds. 1D NOE experiments have been useful in understanding the structure of 1,3,5‐tris(N‐methylenzimidazolyl)benzene.
