Gyton M, Sajjad M, Storm D, Altus K, Goodall J, Johnson C, et al.
J Am Chem Soc . 2025 Feb; 147(10):8706-8719. PMID: 40000373
The known complex [Ir(Bu-PONOP)MeH][BAr], [Bu-PONOP κ-2,6-(BuPO)CHN); Ar = 3,5-(CF)(CH); 131, 8603], is a robust precursor for single-crystal to single-crystal (SC-SC) C-H activation of methane and ethane at 80 °C. This...

stabilization of known, but solution unstable, methylidene complex [Ir(Bu-PONOP)(=CH)][BAr ] allows single-crystal to single-crystal solid/gas reactivity associated with the {Ir=CH} group to be studied. Addition of H results in [Ir(Bu-PONOP)(H)][BAr...

The reaction of [Ir(IPr)H][BAr] (; IPr = 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene; BAr = B{CH(3,5-CF)}) with ZnMe proceeds with CH elimination to give [Ir(IPr)(IPr')(ZnMe)H][BAr] (, where (IPr') is a cyclometalated IPr ligand). reacts with...

In order to establish design criteria for Rh C-H borylation catalysts, analogues of the successful catalyst [Rh(Ind)(SIDipp)(COE)] (Ind = η-indenyl, SIDipp = 1,3-bis(2,6-diisopropylphenyl)-4,5-dihydroimidazol-2-ylidene, and COE = -cyclooctene) were synthesized by...

Using single-crystal to single-crystal solid/gas reactivity the gold(I) acetylene complex [Au(L1)(η-HC≡CH)][BAr ] is cleanly synthesized by addition of acetylene gas to single crystals of [Au(L1)(CO)][BAr ] [L1=tris-2-(4,4'-di-tert-butylbiphenyl)phosphine, Ar=3,5-(CF)CH]. This simplest...
