摘要：

[PdMe2(tmeda)] (1) reacts with pentafluoropyridine in the presence of water and triethylamine to give the aryloxy compound [PdMe(OC5NF4)(tmeda)] (2). The structure of 2 has been determined by X-ray crystallography. The palladium oxygen distance to the aryloxy ligand is 2.0368(14) Angstrom. Treatment of 2 with Me3SiCl effects the cleavage of the palladium oxygen bond and the silane 4-C5NF4(OSiMe3) (3) is formed. (C) 2003 Elsevier Science B.V. All rights reserved.
