Reaction of (TPP)Fe{sup III}Cl in dichloromethane with LiHBEt{sub 3} yields (TPP)Fe{sup III}Et. Reduction of (TPP)Fe{sup III}R to ((TPP)Fe{sup II}R){sup {minus}} (R = n-propyl, ethyl) by either LiHBEt{sub 3} or KHB(i-Bu){sub 3} can be accomplished in benzene/tetrahydrofuran solution, where electron exchange between the iron(III) and iron(II) alkyls is rapid. ((TPP)Fe{sup II}R){sup {minus}} is diamagnetic and is reoxidized by dioxygen by (TPP)Fe{sup III}R.
