A novel method for the direct synthesis of mono- RCCH (R = C6H5, 4-CH3OC6H4, naphthalen-1-yl, etc.) and bis-arylated alkynes RCCR utilizing catalytically activated CaC2 as the alkyne component has been described. This fluoride-activated cross coupling reaction provides advantages over existing methods regarding operational simplicity, use of readily available starting materials, and low cost. In the experiment, the researchers used many compounds, for example, 4-Iodo-1,2-dimethoxybenzene (cas: 5460-32-2Recommanded Product: 5460-32-2).
4-Iodo-1,2-dimethoxybenzene (cas: 5460-32-2) belongs to iodide derivatives. Generally organic iodides can be divided into two classes of alkyl iodides and aryl iodides. Typical reactions of alkyl iodides include nucleophilic substitution, elimination, reduction, and the formation of organometallics. Organoiodine lubricants can be used with titanium, stainless steels, and other metals which tend to seize up with conventional lubricants: organoiodine lubricants can be used in turbines and spacecraft, and as a cutting oil in machining.Recommanded Product: 5460-32-2
