摘要

The synthetic efforts that yielded the first stable [4]-ncirculene, 1,8,9,16-tetrakis(trimethylsilyl)tetra-cata-tetrabenzoquadrannulenen(TMS4-TBQ, 1), are reported. The synthesis and characterizationnof different intermediates are described. The cyclotrimerization of the keynprecursor tetraalkyne was explored using Rh(I), Ni(0), and Co(I) catalysts.nThe ultimate product 1 was isolated only after oxidative demetalation ofncobalt complexes.
