In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Oligomerization of butadiene with (η-C5R5)Ru(II) complexes; stoichiometric and catalytic chemistry, published in 1992-04-28, which mentions a compound: 92390-26-6, mainly applied to cyclopentadienylruthenium octatriene preparation catalyst oligomerization; ruthenium octatriene cyclopentadienyl preparation reaction, Product Details of 92390-26-6.

Treatment of (η-C5R5)Ru(η-butadiene)X (R = H, Me; X = Br, Cl) with butadiene, in the presence of silver triflate, yielded the corresponding cationic complexes I and II with 1,3,7-octatriene ligands, produced from the C-C bond formation at both the terminal carbon atoms of two mols. of butadiene. In the pentamethylcyclopentadienyl system II, the octatriene ligand was cyclodimerized to 1,5-cyclooctadiene when treated with CO. The ligand structure was elucidated by NMR spectroscopy. Catalytic reactions on these systems have also been studied. Thus, treatment of 1,3-butadiene with the octatriene complexes as catalysts afforded 1,5-cyclooctadiene (with II as catalyst) or a mixture of linear dodecatetraenes (with I as catalyst).

Keywords: cycloaddition alkadiyne nitrile ruthenium catalyst bicyclic pyridine preparation. We’ll tell you more about this compound (cas:92390-26-6).

In the presence of a catalytic amount of [Cp*RuCl(cod)] (Cp* = pentamethylcyclopentadienyl, cod = 1,5-cyclooctadiene), 1,6-diynes were allowed to react chemo- and regioselectively with nitriles bearing a coordinating group, such as dicyanides or α-halo nitriles, at ambient temperature to afford bicyclic pyridines. Careful screening of nitrile components revealed that a CC triple bond or heteroatom substituents, such as methoxy and methylthio groups, acted as the coordinating groups, whereas C=C or C=O double bonds and amino groups failed to promote cycloaddition This suggests that coordinating groups with multiple π-bonds or lone pairs are essential for the nitrile components.
