of the soft acidic noble metal catalyst and affords products featuring an additional versatile CI bond. Similar strategies for replacing ynophilic cationic gold(I) complexes in oxidative goldcatalysis with likewise ynophilic stoichiometric electrophiles would enable the development of new synthetic methods.

ahost for organizing dipolar molecular rotor guests into regular trigonal arrays. Inclusion of molecular rotors with transversely dipolar rotators into TPP channels is followed by solid‐state nuclear magnetic resonance, diifferential scanning calorimetry, X‐ray diffraction, and dielectric spectroscopy. The more polar of the two rotors does not form an inclusion. The second rotor forms two different
