| Summary: | 碩士 === 東海大學 === 應用化學系 === 82 === The electrochemistry of nickel(I) tetraamine complexes, and the
reactions of the nickel(I) complexes,[NiL]+,with alkyl halides
have been investigated in nonaquous media containing
tetrabutylammoniun perchlorate. The reaction is proposed to
occur in two steps,the first and rate-determining step being
one-electron transfer from [NiL]+ to RX,by either halogen atom
transfer or inner-sphere electron transfer to yield an alkyl
radical R‧.The latter is captured by [NiL]+,in the second and
more rapid reaction. The current/potential curves of the
electrocatalytic reaction were analyzed to obtain the slope of
the reactions fort-C4H9 ＞ s-C4H9 ＞ n-C4H9 ＞i-C4H9 are
consistent with a radical and inner-sphere mechanism.
