Novel Cr(iii) catalysts supported by linear phosph(iii)azanes of the type R1R2N-P(Ph)-NR3-P(Ph)-NR4R5 have been prepared, all of which, upon activation with MMAO-3A, are highly active for ethene tri-/
BESTIMMUNG DER IONENPAAR-BASIZITAT VON LITHIUM- UND KALIUMAMIDEN

Ion pair basicities of lithio and potassio salts of some secondary amines were determined by equilibration with benzyl compounds.With these bases it is possible to span a range of about 19 pK-units from pK = 27 up to 46.The structural dependence of thermodynamic as well as kinetic basicity is discussed.Some new effective amide bases for preparative purposes are recommended.For the first time the pK-value of toluene has been determined by direct equilibration.It amounts to 40.7 in tetrahydrofuran.
