Whereas reaction of (1) with Ph2PCH2PPh2 (dppm) in ethanol (1:1 molar ratio) gives mer--dppm, the corresponding reaction with Ph2P(CH2)2PPh2 (dppe) gives, after recrystallisation from methanol, the product MeOH.This has been shown by 1H and 31P- n.m.r. spectroscopy to consist of two isomers (3a) and (3b) with bidentate and S-bonded (-)SCOPh groups and the structure of (3b) has been verified by X-ray analysis.The crystals are triclinic, space group P1, with a=10.01(1), b=14.70(1), c=18.52(1) Angstroem, α=75.2(3), β=83.6(3), and γ=73.5(3) deg.Reaction of compound (1) with an excess of PMe2Ph gives an isomeric mixture of mer- whereas shaking cis- in benzene or methanol for short periods with gives the facial isomer.If cis- is shaken with in methanol for several hours, however, the cation (+) can be isolated by addition of Na.
