Addition of 1.1.1-propellane (111P) to (Ph3P)3MCl2(M = Ru, Os) afforded 3-exo-methylenecycloalkylidene complexes (Ph3P)2Cl2M═(cC4H4)═CH2(M = Ru,1-PPh3; M = Os,4-PPh3) via electrophilic ring opening. When they were combinedin situor when they were isolated, both1-PPh3and4-PPh3were competent at the ROMP of norbornene. Phosphine substitution of1-PPh3with PcHex3generated (cHex3P)2Cl2Ru═(cC4H4)═CH2(1-PcHex3), which was competent at norbornene ROMP and ring-closing metathesis. Similarin situaddition of tetracyclo[3.3.1.13,7.01,3]decane (i.e., 1,3-dehydroadamantane,AdP) to (Ph3P)3RuCl2yielded (Ph3P)2Cl2Ru═C{C9H14) (3-PPh3), a cyclohexylidene derivative with related reactivity. Self-metathesis of1-PPh3produced (Ph3P)2Cl2Ru═(cC4H4)═RuCl2(PPh3) (2-PPh3), which was structurally characterized. The use of13C-labeled111P*enabled identification of several alkylidene resonances in13C NMR spectra.
