Safety [ edit ] In 1971 in the U.S. State of California, their department of agriculture reported, "Dichlobenil kills the roots of many species, but not all; further, the killing does not extend much beyond the portion actually soaked."

Dppf readily forms metal complexes. [2] The palladium derivative, (dppf)PdCl 2, which is popular for palladium-catalyzed coupling reactions, is prepared by treating dppf with the acetonitrile or benzonitrile adducts of palladium dichloride: [2] Substitution of the phenyl substituents in dppf leads to derivatives with modified donor-acceptor properties at the phosphorus atoms.
Typical nitrile ligands are acetonitrile, propionitrile, and benzonitrile.The structures of [Ru(NH 3) 5 (NCPh)] n+ have been determined for the 2+ and 3+ oxidation states. Upon oxidation the Ru-NH 3 distances contract and the Ru-NCPh distances elongate, consistent with amines serving as pure-sigma donor ligands and nitriles functioning as pi-acceptors.
Typically, aryl nitriles are produced by ammoxidation. [2] 3-Chlorobenzonitrile can also be produced by dehydration of the aldoxime of 3-chlorobenzaldehyde. [3]It can also be produced by heating 3-chlorobenzylamine and iodine in ammonium acetate aqueous solution.
Due to these hazards, diazonium compounds are often not isolated. ... Illustrative is the preparation of benzonitrile using the reagent cuprous cyanide:
