| titleOfInvention | Dialkylaminopropyl phosphines prodn. - by catalytic reduction then reductive alkylation of corresp. 2-cyanoethyl phosphines |
| abstract | Dialkylaminoprupylphosphines of formula (I) (R)2NCH2CH2CH2 3-nP(R')n (I) (R = 2-8 C alkyl; R'=1-8C alkyl, aryl or alkaryl, n = 0, 1 or 2) is prepd. by reacting cpds. of formula (II) in admixture with a Co carbonyl (esp. Co2(CO)8 or Co cpds. capable of forming catalytically active carbonyls under the process conditions or a reaction prod. of such cpds. with (II) opt. together with free (II), the P:Co atom ratio being 10-0.5:1 with H2 at a partial pressure >1 atm. in presence of CO at partial pressure >1 atm. and of a 2-8C aliphatic aldehyde or ketone (uses at mole ratio to (II) >6) the temp. being 100-250 degrees C. (I) from complexes with transition metals which are catalysts e.g. for hydroformylation, aldehyde hydrogenation, hydrosilylation and diolefin oligomerisation. Process is simple and economic and (I) may be produced as their Co complexes in a form almost ready for use as catalysts. |
