摘要：

The title reaction (10-15 mol % of (t-BuO)(3)W-(dropC-t-Bu), chlorobenzene, 80 degreesC) is applied to octahedral and square-planar 18- and 16-valence-electron rhenium, ruthenium, and platinum complexes with cis- or trans-Ph2P(CH2)(6)CdropCCH(3) ligands. NMR analyses show ca. 90-70% educt conversions, and 17-membered diphosphine chelates have been isolated in 59-47% yields and crystallographically characterized.
