β-Boration of α,β-unsaturated carbonyl compounds in ethanol and methanol catalyzed by CCC-NHC pincer Rh complexes
Reilly, Sean W.,Akurathi, Gopalakrishna,Box, Hannah K.,Valle, Henry U.,Hollis, T. Keith,Webster, Charles Edwin
, p. 32 - 38 (2016)
Quantitative β-boration of α,β-unsaturated carbonyl compounds was achieved utilizing the eco-friendly solvent EtOH along with MeOH at room temperature in 1 h, by a CCC-NHC pincer Rh complex mixture. Substrates with β-substituents were successfully convert
Addition and coupling reactions of bis(pinacolato)diboron mediated by CuCl in the presence of potassium acetate
Takahashi, Kou,Ishiyama, Tatsuo,Miyaura, Norio
, p. 982 - 983 (2000)
The addition of bis(pinacolato)diboron [(Me4C2O2)B-B(O2C2Me 4)] to α,β-unsaturated ketones, esters, nitriles, or terminal alkynes and the coupling with allyl chlorides were carried out in DMF at room temperature in the presence of CuCl and AcOK. The transmetalation from boron to copper generating a B-Cu species was proposed as the key step of the reactions.
Platinum catalysed 3,4- and 1,4-diboration of α,β-unsaturated carbonyl compounds using bis-pinacolatodiboron
Bell, Nathan J.,Cox, Andrew J.,Cameron, Neil R.,Evans, John S. O.,Marder, Todd B.,Duin, Marcel A.,Elsevier, Cornelis J.,Baucherel, Xavier,Tulloch, Arran A. D.,Tooze, Robert P.
, p. 1854 - 1855 (2004)
Bis-pinacolatodiboron reacts with α,β-unsaturated carbonyl compounds to give 1,4- and unprecedented 3,4-additions in the presence of a second generation Pt(0) catalyst at ambient temperature.
β-Borylation of conjugated carbonyl compounds with silylborane or bis(pinacolato)diboron catalyzed by Au nanoparticles
Fragkiadakis, Michael,Kidonakis, Marios,Stratakis, Manolis
, p. 8921 - 8927 (2020/11/23)
Conjugated aldehydes and ketones undergo reaction with Me2PhSiBpin (pin: pinacolato) catalyzed by Au nanoparticles supported on TiO2 forming exclusively the β-borylation products, via the intermediate formation of the labile silaboration adducts. This chemoselectivity pathway is complementary to the so far known analogous reaction catalyzed by other metals, where β-silylation occurs instead. β-Borylation also occurs with pinBBpin under identical reaction conditions in a variety of conjugated carbonyl compounds, including esters and amides which are unreactive in their attempted Au-catalyzed silaboration.
