| Abstract: | CO2, COS, and SCNPh react under very mild conditions with the copper(I)-tetrahydroborate complexes (PR3)2Cu(η2-BH4)] (R = Ph, Cy); CO2 and COS give the complexes (PR3)2Cu(η2-O2CH)] and (PR3)2Cu(η2-OSCH)] respectively, whereas SCNPh gives the η2-dithiocarbamate complexes (PR3)2Cu-(η2-S2CNHPh)]. Addition of PPh3 under CO2 to solutions of (PPh3)2Cu-(η2-BH4)] gives (PPh3)3Cu(η1-O2CH)] while addition of PPh3 and NBu4ClO4 under CO2 gives (PPh3)3Cu(η-O2CH)Cu(PPh3)3] ClO4. |
