The adsorption structure and binding of phenyl isocyanide (PNC), 2,6-dimethyl phenyl isocyanide (DMPNC), and benzyl isocyanide (BZI) on gold nanoparticle surfaces have been studied by means of surface-enhanced Raman scattering (SERS). PNC, DMPNC, and BZI have been found to adsorb on gold assuming a standing geometry with respect to the surfaces. The presence of the nu(CH) band in the SERS spect...
Arynes are found to be facilely inserted into bis(pinacolato)diboron by using a platinum-isocyanide catalyst, affording diverse 1,2-diborylarenes, which can be converted into o-terphenyls via Suzuki-Miyaura coupling reaction.
The marine natural product dysibetaine was synthesized in racemic form from a levulinic acid derivative using a convertible isocyanide and an ammonium acetate in the Ugi 4-center-3-component condensation reaction.
An unexpected formation of cyclic α-alkoxy isothioureas has been achieved. As is known, the heterocyclic imines 2,5-dihydro-1,3-thiazoles are convertible to bisamides with the aid of a carboxylic acid and an isocyanide (Ugi reaction). Herein, it is shown that 2,5-dihydro-1,3-thiazole S-monoxides-the respective α-sulfinyl imines-are characterized by an altered reaction behavior. In a hitherto un...
Chiral gold( i ) isocyanide complexes [Au( p -C 6 F 4 OR 1 )( -CNC H (O 2 CC )] with R , or both being ( )-2-octyl, display an interesting and unprecedented response to mechanical thermal stress.
The coordination chemistry of 1,1'-diisocyanoferrocene (1) was investigated. Its reaction with Cr(CO)5(THF) (2 equiv) affords (1)[Cr(CO)5]2, which exhibits eclipsed cyclopentadienyl rings with a synclinal arrangement of the two substituents. 1 behaves like an aryl isocyanide in this compound according to IR spectroscopic data, and its oxidation leads to a marked decrease of net electron donor a...
We report a survey of the reactivity of the first isolable iron-hydride complexes with a coordination number less than 5. The high-spin iron(II) complexes [(beta-diketiminate)Fe(mu-H)] 2 react rapidly with representative cyanide, isocyanide, alkyne, N 2, alkene, diazene, azide, CO 2, carbodiimide, and Brønsted acid containing substrates. The reaction outcomes fall into three categories: (1) add...
