Herein, a novel crossover reaction of Cu-based carbene, olefin, and tert-butyl hydroperoxide (TBHP) was well developed, leading to γ-peroxy esters and 1,4-dicarbonyl compounds.
Abstract A highly efficient intermolecular mutual addition of aromaticaldehydes with ethyl acrylate was developed by using tris(4-methoxylphenyl)phosphine as the catalyst. The reaction corresponds to the construction of 1,4-dicarbonyl compound and allylic alcohol fragments, which also provides a new way to form C-C bond. GRAPHICAL ABSTRACT

The present invention relates to a hydrazine derivative represented by the general formula (I):
(wherein each of Ar¹ and Ar² is a substituted or unsubstituted phenyl group, a substituted or unsubstituted heteroaryl group, or the like, R¹ is an alkyl group or the like, and A is a divalent radical having -C=N-N- or -CH-NH-N- as a fundamental skeleton), which is a useful compound as an agricultural and horticultural insecticide.
