Synthesis of dicyanomethyl and nitro substituted p-polyphenyls and their salts was written by Zauhar, Joseph;Bandrauk, Andre D.;Truong, Kim D.;Michel, Andre. And the article was included in Synthesis in 1995.Safety of 4,4′-Bipiperidine dihydrochloride This article mentions the following:
A one-step, medium-scale synthesis of several novel dicyanomethyl and nitro substituted p-polyphenyls from 4,4′- or 4”-diiodo-p-polyphenyls and from 4-iodo-4′- or 4”-nitro-p-polyphenyls, resp., and sodium malononitrile using a palladium catalyst is reported. A number of organic cation salts of these extended 蟺-electron systems are likewise described. In the experiment, the researchers used many compounds, for example, 4,4′-Bipiperidine dihydrochloride (cas: 78619-84-8Safety of 4,4′-Bipiperidine dihydrochloride).
4,4′-Bipiperidine dihydrochloride (cas: 78619-84-8) belongs to piperidine derivatives. Piperidine is a metabolite of cadaverine, a polyamine found in the human intestine. Piperidine derivatives are being utilized in different ways as anticancer, antiviral, antimalarial, antimicrobial, antifungal, antihypertension, analgesic, anti-inflammatory, anti-Alzheimer, antipsychotic and/or anticoagulant agents.Safety of 4,4′-Bipiperidine dihydrochloride
