Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 1486-28-8, Name is Methyldiphenylphosphine, molecular formula is C13H13P, belongs to chiral-phosphine-ligands compound. In a document, author is Tang, Yang, introduce the new discover, SDS of cas: 1486-28-8.
Facile synthesis of stereoregular helical poly(phenyl isocyanide)s and poly(3-hexylthiophene)-block-poly(phenyl isocyanide) copolymer using chiral pi-allylnickel complexes as initiators
Living polymerization of achiral phenyl isocyanide using a simply prepared chiral pi-allylnickel complex as initiator was found to proceed in helix-sense-selective manner. The polymerization of achiral phenyl isocyanide, 4-isocyanobenzoyl-2-aminoisobutyric acid hexyl ester (1a) produced optically active helical poly-1a(m) (L or D) whose chirality totally come from the helical conformation without containing any other chiral atoms. The monomer-structural effect on the helix-sense-selectivity was examined and indicated the long alkyl group in the monomer is not essential for the helix-sense-selective polymerization. The effect of chiral phosphine ligand was also investigated. The success of the helix-sense-selective polymerizations indicated the high activity of pi-allylnickel complexes. Finally, polymerization of 2,5-dibromo-3-hexylthiophene (3HT) and subsequent addition of 1a in the presence of chiral pi-allylnickel complex as a single catalyst afforded P3HT(m)-b-poly-1a(n) with nonhelical P3HT and helical poly(phenyl isocyanide) (PPI) segments, which may be used as unique chiral organic materials in the future.
