摘要
Abstract Conceptual principles for operation of a molecular motor stipulate that such a species must consist of an energy‐consuming catalyst that exhibits within its mechanism temporal overlap of successive catalytic cycles, so as to induce irreversible intramolecular motion during operation. The exothermic hydration reaction of MeCOCHCNCMe 3 brought about by catalyst HO 2 CCH 2 OCMe(CO 2 H) 2 qualifies as such a process, in the form of serial conversion between canonical carboxylic anhydride structures within the catalyst. The steady‐state kinetic behavior and inactivation by methanol demonstrate the operation of an appropriate repetitive catalytic loop in this case. Copyright © 2003 John Wiley & Sons, Ltd.
