High-Resolution Solid-State13C NMR Studies on Molecular Motions and Solid-State Polymerization of Octatetraynes

Autor: Kikuko Hayamizu, Hiro Matsuda, Hajime Kawanami, Naoto Kikuchi, Takanori Doi, Hachiro Nakanishi, Shuji Okada

Publikováno v: Bulletin of the Chemical Society of Japan. 68:791-802

The effects of monomer alignment on the solid-state polymerizations of five octatetraynes and a butadiyne to produce polydiacetylenes were studied. Structural relaxations of the resulting polymers were found to occur over long time intervals. Solid-s

Publikováno v: Molecular Crystals and Liquid Crystals Science and Technology. Section A. Molecular Crystals and Liquid Crystals. 247:99-109

Since solid-state polymerization reaction of symmetrically-substituted octatetrayne derivatives can start from both 1,4- and 5,8-positions in the same column of the monomers in crystals, deterioration of crystallinity seemed to occur to some extent i

Autor: Tamon Okano, Jitsuo Kiji, Takanori Doi

Publikováno v: ChemInform. 29

The hydrophilic palladium complex efficiently catalyzes the allylation of carbonyl compounds with allyl chlorides or allyl alcohols and SnCl2 under aqueous-organic biphase conditions, which allow us easily to separate the product and to recover the o
