TL;DR: In this article, the four methylene bridges of p-tert-butylcalix[4]arene are replaced by sulfide linkages, which can be easily synthesized in a single step (54%) by heating a mixture of ptertbutylphenol, elemental sulfur S8 and NaOH in tetraethylene glycol dimethyl ether with concomitant removal of the resulting hydrogen sulfide.
Journal ArticleDOI
Ruthenium Complex-Catalyzed Direct Ortho Arylation and Alkenylation of 2-Arylpyridines with Organic Halides
TL;DR: The ortho position of the aromatic ring of imino group substituted aromatic compounds is directly arylated and alkenylated with organic halides in the presence of a catalytic amount of a ruthenium(II)-phosphine complex.
Journal ArticleDOI

Nobuhiko Iki,Chizuko Kabuto,Takanori Fukushima,Hitoshi Kumagai,Haruhiko Takeya,Setsuko Miyanari,Tsutomu Miyashi,Sotaro Miyano +7 more
TL;DR: In this paper, a practical method for the synthesis of p-tert-butylthiacalix[4]arene (TC4A), in which the methylene bridges of C4A are replaced by epithio groups, is presented by heating a mixture of ptert butylphenol, elemental sulfur S8, and NaOH as a base catalyst in tetraethylene glycol dimethyl ether.
Journal ArticleDOI
Can Thiacalixarene Surpass Calixarene
Nobuhiko Iki,Sotaro Miyano +1 more
TL;DR: In this paper, the authors present the results of their own study to demonstrate the potentials over the limits of the conventional calixarenes, putting emphasis on the indispensable role of the bridging sulfur.
Journal ArticleDOI
Selective oxidation of thiacalix[4]arenes to the sulfinyl- and sulfonylcalix[4]arenes and their coordination ability to metal ions
Nobuhiko Iki,Hitoshi Kumagai,Naoya Morohashi,Kohki Ejima,Mitsuharu Hasegawa,Setsuko Miyanari,Sotaro Miyano +6 more
TL;DR: In this paper, the four methylene birdge of calix[4]arenes are replaced by sulfide linkages, and they were selectively oxidized to sulfinyl- or sulfonylcalix[ 4]arene under mild conditions with control of the stoichiometry of the oxidant.
