The cross-couplingreactions of 3,6-dihalopyridazines with triaryl- or triheteroarylbismuthcompounds were performed under palladium catalysis. The reaction was highly chemoselective, affording functionalized aryl- or heteroarylpyridazinyl chlorides in moderate to good yields.

Ag(I) (M) salts of weakly coordinating anions (PF6–, SbF6–, and OTf–), composed of a cationic substructure of rhombic cage (M)4(L)4 units linked by Sb/Bi–M bonding. The greater Lewis acidity of Bi compared to Sb can, however, allows anion···Biinteractions to overcome Bi–metal bonding in the case of BF4–, leading to collapse of the MOF structure (which is also seen where harder metals like Li+ are employed)

formation of molecular and extended 2D capsule arrangements between the heavier Group 15 tris(3-pyridyl) linkers Sb(3-py)3 and Bi(3-py)3 and the metallo-porphyrins MTPP (M = Zn, Mg; TPP = tetraphenylporphyrin, 3-py = 3-pyridyl) is the first study involving heavier Group 15 pyridyl linkers. The increase in C–E bond length in the E(3-py)3 linkers moving down Group 15 (fromE = P, to Sb, to Bi) can be used
