N2 - The bis(palladium(II)-(R)-alpha-methylbenzylamine) diastereomers of the (R*, R*)-(+/-)-form of the linear tetra(tertiary phosphine) 1,1,4,7,10,10-hexaphenyl-1,4,7,10-tetraphosphadecane, (R-C) (R-P,R-P)- and (R-C)(S-P,S-P)-(4), are readily separated because of a large difference in their solubilities in moderately polar solvents. The single-crystal X-ray structure of (R-C)(S-P,S-P)-(4), along with published data on (R-C)(R-P,R-P)-(4), suggests that the ease of separation is due to conformational differences in the two organometallic rings present in each diastereomer (delta or delta lambda) in the solid state.
