Alkylation of 2‐hydroxypyridine, 2‐pyridinethiol, 2‐hydroxy‐4‐methylquinoline, phthalimide and pyrazole with propargyl bromide gave a series of alkynes in high yield. These alkynes were reacted with the chloroplatinum(II) compounds trans ‐[PtCl 2 (PPh 3 ) 2 ] and cis ‐[PtCl 2 (dppe)] to afford the respective trans‐ and cis‐ bis(alkynyl)platinum(II) complexes, which were characterised by spectroscopic analysis and by X‐ray diffraction. The platinum(II) complexes containing the thiopyridyl‐ and pyrazolyl‐substituted alkynes react with 1 or 2 equiv. of [Ag(NO 3 )(PPh 3 )] to give dimetallic Pt II /Ag I complexes.(© Wiley‐VCH Verlag GmbH & Co.
