Synthesis of symmetric and unsymmetric 1, 4-bis ( p-R-phenylethynyl) benzenes via palladium/copper catalyzed cross-coupling and comments on the coupling of aryl halides with terminal alkynes.
A flexible and free standing conjugated microporous polymer (CMP) membrane was prepared using a polyvinylpyrrolidone (PVP) electrospun membrane as a template. The PVP nanofibers of the template membrane were coated with a thin layer of the CMP through the in
[reaction: see text] The first total synthesis of martinellic acid, a naturally occurring bradykinin receptor antagonist, via a CuI-catalyzed coupling reaction of beta-amino ester 6 with 1,4-diiodobenzene and a guanylation reaction of secondary amine 3 under mild conditions as key
