Halocarbonyl Compounds

The halodiazoacetates are a group of synthetically useful halogenated diazo compounds that can be used in Rh(II)-catalyzed carbenoid reactions. In the reactions between the halodiazoacetates and electron-rich, sterically unhindered alkenes, halocyclopropanes are formed in good to excellent yields. The halodiazoacetates also react well in C–H and Si–H insertion reactions, broadening the synthetic utility of these reactions. The products of the reactions are synthetically useful α-halocarbonyl compounds. Density functional theory (DFT) calculations have given insight into the mechanism of the cyclopropanation and C–H insertion reactions of the halodiazoacetates, and have also shown that the halodiazoacetates have a particularly high kinetic activity.

Membered Transition State

The mechanistic study on the oxidation of 2-propanol by the model complex CpIr [κ2-(N,C)-( NHCMe2–2-C6H4)] (R) is performed using density functional theory (DFT) calculations. It is found that the rate-determining step is the hydrogen migration from 2-propanol to R via a six-membered transition state. The reaction is calculated to be favorable thermodynamically. To further understand the reaction mechanism, some bonding features are discussed, such as the correlation of the geometry of R and the Ir–N π bond involved, the transformation of the nitrogen hybridization, the variation of Ir–N bond distance, and so on.
