Hydrophobic amplification of noncovalent organocatalysis
The effects of hydrogen-bonding organocatalysts and water for the acceleration of epoxide openings with a variety of nucleophiles are additive and lead to excellent yields of the catalyzed reactions in water. The Royal Society of Chemistry 2006.

One-pot Synthesis of Secondary or Tertiary Amines from Alcohols and Amines via Alkoxyphosphonium Salts
Secondary or tertiary amines may be prepared from primary alcohols and primary or secondary amines by treating triphenylphosphine with N-bromosuccinimide (NBS) in the presence of the alcohol at low temperature, followed by addition of the amine and heating for about 1 h.The yield of amine is good to fair, decreasing sharply with sterically congested alcohols and starting amines.
