Reactions catalyzed within inorganic and organic materials and at electrochemical interfaces commonly occur at high coverage and in condensed media, causing turnover rates to depend strongly on interfacial structure and composition. 31608-22-7, Name is 2-(4-Bromobutoxy)tetrahydro-2H-pyran, molecular formula is C9H17BrO2. In a Article，once mentioned of 31608-22-7, 31608-22-7
O-Protected cyanohydrins were found to serve as a source of the nitrile within the intramolecular cobalt-mediated [2+2+2] cycloaddition to pyridines. Several 6-substituted 1,2,3,4,7,8,9,10-octahydrophenanthridines were synthesized using this cycloaddition of diyne-cyanohydrins. By introduction a TMS group a divergent way to such phenanthridine derivatives was elaborated. Georg Thieme Verlag Stuttgart – New York.
