We report here a C–H homoallylation reaction of aromaticketones with methylenecyclopropanes (MCPs) only using a catalytic amount of Fe(PMe3)4. A variety of aromaticketones and MCPs are applicable to the reaction to form ortho-homoallylated aromaticketones selectively via regioselective scission of the three-membered rings. The homoallylated products are amenable to further elaborations, providing

alkylation reaction, in which the coupling of aromatic ketones with alkenes proceeds in the presence of only a simple Fe(PMe3)4 catalyst. The anti-Markovnikov addition of ortho C-H bonds in various ketones occurs with excellent regioselectivity under relatively mild reaction conditions. A strikingly wide variety of alkenes can be used for this reaction, and the high-yielding anti-Markovnikov addition
The invention relates to the use of piperazine compounds of formula (I) or the agriculturally useful salts of piperazine compounds of formula (I) as herbicides, the variables in formula (I) being defined as cited in the claims and the description.
