| Popis: | The zirconium compound, [κ5-N,N,N,N,C-(Me3SiNCH2CH2)2NCH2CH2NSiMe2CH2]Zr (1) , catalyzes the hydroarsination of alkenes with primary arsines, previously unknown substrates for this transformation. Irradiation in the ultraviolet, near-UV, or visible with commercially-available light sources are critical for this catalysis. Styrene substrates are unreactive without irradiation, but Michael acceptors give products in the dark or under irradiation with any source. These observations suggest that the zirconium arsenido intermediate engages in insertion based hydroarsination under photolysis, but the arsenido ligand is nucleophilic without photoexcitation. |
