Reagent for the preparation of phosphonate esters by the Arbuzov reaction; cf Triethyl phosphite, L00339. Has the advantage over primary phosphites that the bulky alkyl groups minimize the product of self-alkylation. For an example (diisopropyl methanephosphonate), see: Org. Synth. Coll., 4, 325 (1963)./n
Convenient means of introduction of an isopropyl group into an aromatic ring by Friedel-Crafts alkylation. Using nitromethane as solvent, rearrangement of existing groups can be avoided: Synthesis, 423 (1972)./n
The complex with CuCl, the "Moser" catalyst, promotes the cyclopropanation of alkenes by diazoalkanes: J. Am. Chem. Soc., 91, 1135 (1969). For comparison with other catalysts, see: Synthesis, 787 (1981)./n
The combination with Pd(OAc)2 is reported to be an efficient catalyst system for cross-coupling of arylboronic acids with both aryl bromides and chlorides: Chem. Eur. J., 6, 1830 (2000)./n
