Abstract

The activation of 1,1-diphenyl-2-propyn-1-ol by complexes [RuCl(η⁶-p-cymene){η²-P,N-Ph₂PCH₂P( [double bond, length as m-dash] NR)Ph₂}]⁺ (1a–d) results in the formation of the unusual tethered (η⁶-arene)–ruthenium(II) derivatives 2a–d, via an unprecedented iminophosphorane–allenylidene coupling process.
