The enthalpy and entropy changes relative to the stepwise reaction of [(triphos)Re(CO) 2 H] with perfluoro-tert-butyl alcohol in CH 2 Cl 2 to give first the hydrogen-bonded adduct [(triphos)Re(CO) 2 Hβ’β’β’HOC(CF 3 ) 3 ] and then the stable non-[a] A. N.
Whenever hydrogen bonding is involved in molecular recognition, the possibility of a proton transfer from the donor to the acceptor arises. In most cases the pK a of the donor is far enough above the pK a of the conjugate acid of the acceptor for it to be clear that no proton transfer will occur. Ho
