Coupling of two phospha-alkyne units via a carbonyl group, in the addition across the RhRh double bond of [Rh2(CO)2(η5-C5Me5)2], crystal and molecular structure of the complex [Rh2(CO)(η5-C5Me5)2{PCRC(O)CRP}](R = adamantyl)
Abstract
The novel ligating unit PCRC(O)CRP (R = adamantyl) has been obtained from two phospha-alkynes RCP on treatment with [Rh2(CO)2(η5-C5Me5)2].
