Four new cyclic and acyclic dicoordinated arsenium salts were obtained by action of AlCl3 and CF3SO3SiMe3 (or CF3SO3inAg) on tricoordinated chloroarsenic precursors.
通过AlCl 3和CF 3 SO 3 SiMe 3(或Ag中的CF 3 SO 3)对三配位氯砷前体的作用,获得了四种新的环状和无环二配位砷盐。

Zirconium-catalyzed hydroarsination with primary arsines

The zirconium compound, [kappa(5)-N,N,N,N,C-(Me3SiNCH2CH2)(2)NCH2CH2NSiMe2CH2]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.
