    • Although 1H NMR spectra of the isopropylzinc alkoxides issued from DMNE, DBAE, and their mixture in deuterated toluene were too complex to be fully interpreted, NMR spectroscopy showed that the isopropylzinc alkoxide issued from the mixture of DMNE and DBAE forms preferentially another complex(es) than when they are alone. Charts and their comments are shown in the Supporting Information
