The preparation of ortho-chelating aminoaryl ligands ([C 6 H 3 (CH 2 NMe 2)-2-R-4]-, abbreviated as C,N) containing a pendant hydroxymethyl group is described. These ligands have been cycloplatinated with cis-PtCl 2 (DMSO) 2 , yielding the corresponding C,N-platinum(II) complexes. The pendant hydroxymethyl substituent is a versatile group for attachment of the organometallic moiety to macromolecules, which has been demonstrated by attaching the C,N-platinum complexes to a dendritic wedge and to C 60 .

The synthesis of C 60 -attached SCS ligands ([C 6 H 2 (CH 2 SPh) 2 -2,6-R-4] ( ) is described. Starting from 4-formyl-SCS-H (2), 1,2-methanofullerene and fulleropyrrolidine SCS ligands were obtained. Subsequent palladation with [Pd(MeCN) 4 ](BF 4 ) 2 afforded the corresponding palladium(II) complexes. #

The reaction of the diamino-ligated dimethylplatinum( II ) complex [ Pt( Me)_,( bpy ) I ( bpy = 2,2'-bipyridyl ) with phenol affords the new complex [ Pt( Me 1 ( OPh ) (bpy) I ( ! ). The X-ray crystal structure of square-planar ! is reported: orthorhombic, space ~oup P2_t2t2 ~ ( No. 19), a = 9.1625 (12)
