3-Sep-2021 News Discovery of Tris(dimethylamino)phosphine

Electric Literature of 1608-26-0, Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 1608-26-0, P[N(CH3)2]3. A document type is Article, introducing its new discovery.

The addition of two moles of a tertiary phosphine ligand PR3 to affords the dinuclear disubstituted iridium(I) complexes . 1H, 13C and 31P and infrared data are consistent with a bent geometry, the CO groups being in cis dispositions and the t-butyl groups in anti dispositions.When R = OMe exchange between this isomer and the trans-anti isomer occurs in solution.For R = Ph one isomer, possibly a trans isomer, which is transformed irreversibly into the cis isomer, is detected.An intermediate complex is observed during substitution, and its spectroscopic data are consistent with the formula .This complex is in equilibrium with the parent complex and , and NMR data suggest that it is an anti isomer.
