متن کاملHelical organization of chiral binaphthyl tetrathiafulvalene primary amides through hydrogen bonding interactions
Chiral tetrathiafulvalenes, (R) or (S), or racemic, (R,S), are obtained from a phosphite-mediated cross coupling reaction of a 1,3-dithiole-2-thione derivative bearing one binaphthol moiety, and are transformed into binaphthol-based tetrathiafulvalene ortho-diamides. The X-ray crystal structures of five intermediate chiral 1,3-dithiole-2-one and 1,3-dithiole-2-thione derivatives reveal the form...
