67 The labeled precursor utilized in the present investigation, 1-deoxy-D-three [ l-2H3,5-2Hl]pentulose (6) was synthesized from 2,4-O-benzylidene-~-[4-~H~] threose, which is available from D[ l-2Hl]arabinitol by standard Reaction of the threose derivative with trideuteriomethylmagnesium iodide in ether then gave a mixture of protected, epimeric pentane tetrols, which was oxidized by the stannylene

The reaction of Fe(CO)5 and L (L = Group Vdonorligand), in the presence of CoCl2 · 2 H2O or CoI2 · 4 H2O as catalyst, results in the synthesis of Fe(CO)4L in good yield. Unusual reactivity patterns for the substitution of CO on Fe(CO)5 by L have been found; for CoI2 as catalyst the reaction rate increases in the order PPh3 ∼ AsPh3 ∼ P(OPh)3 > SbPh3 > PPh2Me > PPhMe2 > P(C6H11)3 > P(OEt)3 > P(n-Bu)3
