Iida, Hiroki; Umebayashi, Naofumi; Yashima, Eiji published the artcile< Photoswitchable organocatalysis in acylation of alcohol using dithienylethene-linked azoles>, SDS of cas: 1003-21-0, the main research area is dithienylethene linked azole preparation photoswitchable organocatalyst acylation alc.
Three novel dithienylethenes bearing azole derivatives were synthesized and found to undergo reversible photocyclization of the dithienylethene units upon alternate irradiation with UV and visible light. Among them, the dithienylethene-linked imidazole and N-phenylimidazole exhibited a relatively high organocatalytic activity for the acylation of 2-decanol with acetic anhydride, and the catalytic activity of the dithienylethene-linked imidazole could be switched by reversible photoinduced cyclization/cycloreversion of the dithienylethene unit.
Tetrahedron published new progress about Acylation. 1003-21-0 belongs to class imidazoles-derivatives, and the molecular formula is C4H5BrN2, SDS of cas: 1003-21-0.
