637031-93-7, Name is 3,3-difluorocyclobutanamine hydrochloride, molecular formula is C4H8ClF2N, Name: 3,3-difluorocyclobutanamine hydrochloride, belongs to benzoxazole compound, is a common compound. In a patnet, author is Kale, Dolly, once mentioned the new application about 637031-93-7.
Facile Access to 2-Substituted Benzoxazoles Using Sawdust Supported N-Heterocyclic Carbene-Ni Complex via C-H Activation
Sawdust supported N-heterocyclic carbene-nickel complex has been prepared by covalent grafting of 1-methyl imidazole in the matrix of chloropropyl modified sawdust followed by reaction with nickel acetate. The resultant NHC-Ni complex was employed as a heterogeneous catalyst for the synthesis of 2-substituted benzoxazoles from benzoxazole and aryl boronic acids following C-H activation strategy. The recycling experiments showed that the complex could be reused for five consecutive runs without significant loss in the yield of products.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 637031-93-7 help many people in the next few years. Name: 3,3-difluorocyclobutanamine hydrochloride.
