Description	Cyclotrimerization reactions of the 9-protected 6-ethynylpurines 4a,b in the presence Ni(COD) 2 or Ni(COD) 2 /PPh 3 gave the 1,2,4- and 1,3,5-tris(purin-6-yl)benzenes 5a,b and 6a,b in moderate to good yields (in a 4:1 to 10:1 ratio). Cyclotrimerization reactions of the 9-protected 6-ethynylpurines 4a,b in the presence Ni(COD) 2 or Ni(COD) 2 /PPh 3 gave the 1,2,4- and 1,3,5-tris(purin-6-yl)benzenes 5a,b and 6a,b in moderate to good yields (in a 4:1 to 10:1 ratio).
