Formation of L-Threonic Acid from L-Ascorbic Acid Oxidative Ring Opening and its Coordination to PtII: X-ray Crystal Structures of [Pt(threonato-O,O)-(PPh3)2] and [Pt(oxalato)(PPh3)2]

The oxidative ring opening of L-ascorbic acid was obtained in three steps giving oxalic and L-threonic acid. The reactions of these acids with the carbonate complex [Pt(CO)3(PPh3)2] yielded two PtII chelates, [Pt(oxalato)(PPh3)2] and the new complex [Pt(threonato-O,O)(PPh3)2], respectively. The X-ray crystal structures of both complexes were determined.
