Direct α-allylation of a variety of ketones and aldehydes with 2-allylisourea took place in the presence of a catalytic amount of a palladium(0) complex under neutral and mild conditions. Scope and limitations of this novel method have been investigated.
A new palladiumcatalysed intramolecular double cyclisation of dienones to cyclic acetals in a single reaction has been described.

Highly dispersed palladium on graphite (Pd/Gr), carbon (Pd/C) and alumina (Pd/Al2O3) have been employed as catalysts in substitutionreactions of allylic esters with nucleophiles such as benzenesulfinate and diethyl malonate anions, and 1-(1-cyclohexen-1-yl)pyrrolidine.
高度分散的钯/石墨(Pd / Gr),碳(Pd / C)和氧化铝(Pd / Al 2 O 3)已用作烯丙基酯与亲核试剂(如苯亚磺酸盐和丙二酸二乙酯)的取代反应中的催化剂, -(1-环己烯-1-基)吡咯烷。
