Amine-Catalyzed Biomimetic Hydrolysis and Condensation of Organosilicate.

A recent review of some of the data used revealed some errors.Specifically, the calculation of the hydrolysis and condensation rate constants are incorrect by roughly a factor of 2, because the starting molarity used for trimethylethoxysilane was actually 2 M, rather than the 4 M that was used in our calculations.Further inspection also showed that individual hydrolysis rate constants for the catalysts tetraethylenepentamine and imidazole were incorrectly calculated.The amended data are summarized in Tables 1 and2.Graphical data are included in Supporting Information.These errors have no adverse effects on the overall conclusions drawn from the work.
