The thiophosphinic amide 2 was prepared in 68 % yield by the reaction of 2,2-dimethyl-1,3-propanediamine with diisopropylchlorophosphine followed by the addition of sulfur. Attachment of the proligand 2 to zirconium was achieved by direct metalation with ZrA C H T U N G T R E N N U N G (NMe 2 ) 4 in
