Table 3. Corrected. Structural Formulas of Tested Aldehydes and Ketones and the Determined k₂ Values of Their Reaction with Urea in PBS at 323 K.

Measured at 293 K instead of 323 K.

1,1,3,3-Tetramethoxypropane in PBS was stirred at pH 2 for 30 min at RT after which the pH was adjusted (to pH 2 or 7.4), and urea was added to the reaction mixture.

2,5-Dimethoxytetrahydrofuran was stirred in PBS at pH 2 for 30 min at 293 K after which the pH was adjusted (to pH 2 or 7.4), and urea was added to the reaction mixture.

Measured both in PBS and 1:1 PBS/DMSO as solvent at 323 K.
