Beyond Fe-only hydrogenases: N-functionalized 2-aza-1,3-dithiolates Fe2[(SCH2)2NR](CO)x (x = 5, 6)
Abstract
Primary amines undergo chloromethylation with
CH2O/SOCl2 to give RN(CH2Cl)2,
which in turn react with
Li2[Fe2S2(CO)6] to give
Fe2[(SCH2)2NR](CO)6; in the
case of R = CH2CHCH2 and
CH2CH2SMe, Me3NO-induced decarbonylation
afforded pentacarbonyl derivatives wherein the pendant functionality is
coordinated to Fe.
