摘要
The reversible uptake Of CO2 by Tp*Zn-OH complexes in alcoholic solutions with formation of Tp*Zn-alkylcarbonate complexes was subjected to a comparative study. Its rate and the stability of its products depend on (1) the substituents in the 3-positions of the pyrazolylborates (phenyl approximate to 3-pyridyl >> t-butyl), (2) the alcohol (CH3OH > C2H5OH). Traces of water seem to be essential for the formation of the Tp*Zn-alkylcarbonates. In solution these are only stable in the presence Of CO2. Two new alkylcarbonate complexes were obtained and characterized by structure determinations.
