摘要
The kinetics of charge transfer complex(CTC) of 2,3,5,6 tetramethoxyl 1,4 benzoquinone(TMOQ) with two alicyclic N donors,piperidine(PD) and morpholine(ML), in methanol, has been investigated by ultraviolet visible spectroscopy. The transformation leads to the formation of substitution products in solution, which have been isolated and characterized as 2,5 diamino 3,6 dimethoxyl 1,4 benzoquinones by 1H NMR, MS, and elemental analysis. The kinetic results of the formation of products indicate that the rate is first order both with the acceptor and the donor. A mechanism of interaction between TMOQ and PD or ML is discussed.
