A mild and efficientsynthesis of N-acylhydrazones has been developed, applying a simple grindstone procedure, leading to a library of 51 examples exhibiting a broad variety of structural features, 21 of them described for the first time in this paper. This methodology works without any organic solvent under the catalysis of acetic acid at room temperature, promotes the formation of essentially pure

This method uses a minimal catalytic amount of cerium(III), is stereoselective, and offers several unique features, such as compatibility with aryl, heterocyclic, alkenyl, and sensitive functional groups as well as the ability to prepare N-acylhydrazones from highly hindered substrates. More strikingly, cerium(III) efficiently mediated the reaction with less reactive substrates such as diaryl and alkyl

The present invention provides a polyolefin-based resin composition containing a crystal nucleating agent having a specific structure, which polyolefin-based resin composition has a superior transparency and whose crystallization is facilitated.
The polyolefin-based resin composition is characterized by comprising, with respect to 100 parts by mass of a polyolefin-based resin, 0.01 to 1 parts by mass of at least one crystal nucleating agent selected from the group consisting of crystal nucleating agents each having a structure represented by one of the following Formulae (1) to (6):
