Friedel-Crafts-type allylation of nitrogen-containing aromatic compounds with allylic alcohols catalyzed by a [Mo3S4Pd(η3-allyl)] cluster.

With the direct use of allylic alcohols as allylating agents, the Friedel-Crafts-type allylic alkylation of nitrogen-containing aromatic compounds catalyzed by a [Mo(3)S(4)Pd(η(3)-allyl)] cluster is achieved. With a 3 mol % catalyst loading in acetonitrile at reflux or 60 °C, a variety of N,N-dialkylanilines and indoles reacted smoothly with allylic alcohols to afford the Friedel-Crafts-type allylation products in good to excellent yields with high levels of regioselectivity.

Nitrogenase model complexes [Cp*Fe(mu-SR(1))2(mu-eta(2)-R(2)N=NH)FeCp*] (R(1) = Me, Et; R(2) = Me, Ph; Cp* = eta(5)-C5Me5): synthesis, structure, and catalytic N-N bond cleavage of hydrazines on diiron centers.

The reactions of [Cp*Fe(mu-SR1)3FeCp*] (Cp* = eta5-C5Me5; R1 = Et, Me) with 1.5 equiv R2NHNH2 (R2 = Ph, Me) give the mu-eta2-diazene diiron thiolate-bridged complexes [Cp*Fe(mu-SR1)2(mu-eta2-R2N NH)FeCp*], along with the formation of PhNH2 and NH3. These mu-eta2-diazene diiron thiolate-bridged complexes exhibit excellent catalytic N-N bond cleavage of hydrazines under ambient conditions.

Highly efficient and regioselective allylation with allylic alcohols catalyzed by [Mo(3)S(4)Pd(eta(3)-allyl)] clusters.

A highly efficient and regioselective allylation reaction of amines and active methylene compounds directly using allylic alcohols under mild conditions catalyzed by the novel cubane-type sulfido [(Cp*Mo)(3)(mu(3)-S)(4)Pd(eta(3)-allyl)][PF(6)](2) clusters has been developed. A variety of allylic alcohols and nucleophiles including amines and active methylene compounds are investigated, and in the case of allylic alcohols bearing substituents at either the alpha- or gamma-position only linear products are obtained.
