Abstract
Abstract Novel polymeric diphosphine coordinates are obtained by reacting a diphosphine alkali alcoholate with an halogenated polymer, and their metal derivatives are obtained by reacting the coordinate with salts or transition metal complexes. These metal polymers can be used as catalysts in catalysis reactions by means of coordination complexes.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
56 words
The method for preparing a polymeric diphosphine coordinate which comprises the step of contacting an alkali metal or alkaline earth metal alcoholate of diphosphine of the formula: ##STR3## wherein Ma is an alkali metal or alkaline earth metal and n is 1 to 4, dissolved in a solvent, with a halogenated polymer suspended in a liquid.
Claim 2
Independent Claim
56 words
The method for preparing a polymeric diphosphine coordinate which comprises the step of contacting an alkali metal or alkaline earth metal alcoholate of diphosphine of the formula: ##STR3## wherein Ma is an alkali metal or alkaline earth metal and n is 1 to 4, dissolved in a solvent, with a halogenated polymer suspended in a liquid.
Claim 3
Dependent Claim
9 words
The method of claim 1 wherein n is 1.
Claim 4
Dependent Claim
31 words
The method of claim 1 wherein said alcoholate and polymer are contacted for 2 to 24 hours at room temperature and then for 0.5 to 6 hours at an elevated temperature.
Claim 5
Dependent Claim
26 words
The method of claim 3 wherein said alcoholate and polymer are contacted for 4 to 8 hours at room temperature and 1-3 hours at elevated temperature.
Claim 6
Dependent Claim
25 words
The method of claim 1 wherein said halogenated polymer is a halogenated polyvinylic, polybutadienic or polystyrenic polymer and the halogen is chlorine, bromine or iodine.
Claim 7
Dependent Claim
33 words
The method of claim 1 wherein said halogenated polymer is a chlorinated or brominated polymer and said contacting takes place in the presence of a 10--100% stoichmetric excess of an alkali metal iodide.
Claim 8
Dependent Claim
17 words
The method of claim 1 wherein said solvent and said suspending liquid are non-protic and non-halogenated liquids.
Claim 9
Dependent Claim
45 words
The method of claim 1 wherein said alcoholate is prepared by contacting an alkali metal or alkaline earth metal diphenyl phosphine with epichlorohydrin, and wherein the resulting alcoholate is contacted with the halogenated polymer without isolation from the reaction mixture in which it is prepared.
Claim 10
Dependent Claim
26 words
The method of claim 1 further comprising the step of contacting the resulting coordinate with a transition metal salt or complex thereof in an inert solvent.
Claim 11
Dependent Claim
26 words
The method of claim 9 wherein the temperature is raised during the period of contact between the coordinate and the transition metal salt or complex thereof.
Claim 12
Dependent Claim
12 words
The method of claim 1 wherein said polymer is a polystyrenic polymer.
Claim 13
Dependent Claim
12 words
The method of claim 1 wherein said halogenated polymer is chloromethylated polystyrene.
