  Rearrangements of the unsaturated ligand 1,1-bis(diphenylphosphinomethyl)ethene and its chalcogenides and group VI metal carbonyl complexes

  摘要：

  In contrast to the behaviour of other unsaturated organophosphines, treatment of the new ligand (Ph2PCH2)2C = CH2 with Ph2PH in the presence of KOBu(t) does not result in addition to the double bond; instead, an allylic rearrangement occurs to give cis and trans Ph2PCH = C(CH3)CH2PPh2 in a 3:7 ratio. In the case of (Ph2P(E)CH2)2C = CH2 [E = S, Se] only the trans isomer is obtained from this reaction, while under similar conditions (CO)4M(Ph2PCH2)2C = CH2 [M = Cr, Mo, W] yields only a cis product in which the two phosphorus atoms remain chelated. The products of these and related reactions are characterized by elemental analysis and C-13 and P-31 NMR spectroscopy.
