Preparation and reactivity of a series of bis(phosphine) rhodium(I) alkoxides stabilized by intramolecular olefin coordination are reported. Rh(PEt3)2[kappa1:eta2-OCRR'(CH2)nCH=CH2]} (n = 1, 2) were prepared via alcoholysis of Rh(PEt3)2[N(SiMe3)2]} by the corresponding alcohols HOCRR'(CH2)nCH=CH2. The in situ generated Rh(PEt3)2[kappa1:eta2-OCRR'(CH2)2CH=CH2]} were not stable at ambient temperatures
