Claims
- 1. A compound of the formula
- (R.sup.1).sub.2 P--(N).sub.x --(P).sub.y --N--P(R.sup.1).sub.2
- where x and y are independently 1 or 0 and R.sup.1 is independently an aryl, alkyl, allcoxy, amido or substituted derivative thereof and at least one of the R.sup.1 groups is an o-anisyl.
- 2. A compound as claimed in claim 1, having the formula
- (R.sup.1).sub.2 PNR.sup.2 P(R.sup.1).sub.2
- where R.sup.2 is a hydrogen, a hydrocarbyl or hetero group.
- 3. A compound as claimed in claim 2 having the formula
- (Ph).sub.2 PN(nBu)P(o-anisyl).sub.2.
- 4. A compound as claimed in claim 2 wherein all R.sup.1 groups are o-anisyl.
- 5. A compound as claimed in claim 4 wherein R.sup.2 is methyl.
- 6. A process for preparing a compound as claimed in claim 4 comprising reacting (o-anisyl).sub.2 PX where X is Cl, Br or F with NH.sub.2 R.sup.2 where R.sup.2 is as defined in claim 2 in the presence of a base.
- 7. A compound of formula II
- L.sub.2 Pd(P--P) II
- where each L is independently a monodentate ligand or L.sub.2 taken together is a bidentate ligand, P--P is a bidentate phosphine ligand having at least two phosphorus atoms joined by a bridging group of the formula --(N).sub.x --(P).sub.y --(N)-- where x and y are independently 1 or 0, provided that when x=0 and y=0 L is not Cl and when L is Cl and P--P is (R.sup.7).sub.2 PN(Me)N(Me)P(R.sup.7).sub.2, R.sup.7 is not alkoxy.
- 8. A compound of formula III
- [L.sup.1.sub.2 Pd(P--P)](A).sub.2 III
- where P--P is as defined in claim 7, L.sup.1 is a neutral monodentate ligand or L.sup.1.sub.2 taken together is a neutral bidentate ligand and A is a weakly or non-coordinating anion or (A).sub.2 together is a weakly or non-coordinating dianion.
