资源简介：
An atom-economical synthesis of arsaalkenes
via a net coupling of aryl arsines with aryl or alkyl isocyanides
at zirconium is presented. Reaction of zirconium arsenido complexes
(N3N)ZrAsHAr [N3N = N(CH2CH2NSiMe3)33–; Ar = Ph, (2) Mes (3)] with aryl and alkyl isocyanides yields
arsaalkene products of the general form (N3N)Zr[NRC(H)As(Ar)].
Two examples (5: R = Mes, Ar = Ph; 6: R
= CH2Ph, Ar = Mes) were structurally characterized. Observation
of intermediates in the reaction and structural characterization of
the previously reported 1,1-insertion product benzylisocyanide with
(N3N)ZrAsPh2 (8), (N3N)Zr[η2-C(PPh2)=NCH2Ph] (9), support the mechanistic hypothesis that these reactions
occur via 1,1-insertion followed by rearrangement.
