Catalytic asymmetric aldol reaction: reaction of aldehydes with isocyanoacetate catalyzed by a chiral ferrocenylphosphine-gold(I) complex
Journal ArticleDOI

Hajime Ito,Tomohisa Saito,Naoya Oshima,Noboru Kitamura,Shoji Ishizaka,Yukio Hinatsu,Makoto Wakeshima,Masako Kato,Kiyoshi Tsuge,Masaya Sawamura +9 more
TL;DR: Reversible mechanochromic luminescence of [(C6F5Au)2(mu-1,4-diisocyanobenzene)] is reported and intermolecular aurophilic bondings presumably play a key role in the altered emission.

TL;DR: A laser light scattering study of the association behavior of the potassium salt of pentaphenyl fullerene in water revealed that the hydrocarbon anions Ph5C60- associate into bilayers, forming stable spherical vesicles with an average hydrodynamic radius and a radius of gyration of about 17 nanometers at a very low critical aggregation concentration.
Journal ArticleDOI
Stacking of conical molecules with a fullerene apex into polar columns in crystals and liquid crystals
TL;DR: This work shows that the attachment of five aromatic groups to one pentagon of a C60 fullerene molecule yields deeply conical molecules that stack into polar columnar assemblies, which should be applicable to other molecules and yield a range of new polar liquid crystalline materials.
