Abstract

In the di(organocyanamide) complexes trans-[PtCl2(NCNR2)2] (R = Me 1a, Et 1b), prepared by reaction of PtCl2 with the appropriate NCNR2, the cyanamide ligands, activated by coordination, undergo an unprecedented nucleophilic addition, at room temperature, of an haloalcohol (ClCH2CH2OH/LiBun) or of an alcohol (MeOH) to give the corresponding 2-amino-2-oxazoline cis-[PtCl2{[upper bond 1 start]N[double bond, length as m-dash]C(OCH2C[upper bond 1 end]H2)NR2}2] (R = Me 2a, Et 2b) or trialkylisourea trans-[PtCl2{NH[double bond, length as m-dash]C(OMe)NR2}2] (R = Me 3a, Et 3b) complexes. The X-ray crystal structure of 2b is also reported, indicating a π-bond delocalization along the N[horiz bar, double dot above]C[horiz bar, double dot above]N group of the aminooxazoline ligands.
