- Nano-K2CO3: Preparation, characterization and evaluation of reactive activities
-
A novel base, nano-K2CO3, was easily prepared by ultrafine wet milling. The surface properties and the reactive activities of nano-K2CO3 were characterized. It was found that such a base showed higher basicity than normal K2CO3 and could replace sodium (or potassium) alkoxide to carry out monoalkylation and oximation of active methylene compounds. The nano-K2CO3 could be regenarated and reused 10 times without loss of its reactive activity.

- Sodium borohydride as the only reagent for the efficient reductive alkylation of malononitrile with ketones and aldehydes
-
An efficient and convenient method for the synthesis of primary and secondary monosubstituted malononitriles has been developed. In this method, sodium borohydride in isopropanol has a catalytic effect on the initial condensation between malononitrile and

- MALONONITRILE COMPOUND AND USE THEREOF AS PESTICIDES
-
The present invention relates to a novel malononitrile compound represented by the formula (A): wherein, R1 represents C1 to C6 alkyl that may be substituted with halogen, C2 to C6 alkenyl that may be substituted with halogen, etc; R2 represents hydrogen atom or C1 to C6 alkyl that may be substituted with halogen; R3 represents hydrogen atom or C1 to C6 alkyl; R4 represents hydrogen atom or C1 to C6 alkyl; R5 represents C1 to C6 alkyl that may be substituted with halogen, C3 to C6 alkenyl that may be substituted with halogen, etc , or R4 and R5 may be combined at their terminal and represent ethylene that may be substituted with C1 to C3 alkyl or trimethylene that may be substituted with C1 to C3 alkyl; and Z1 and Z2, which are the same or different, represent oxygen atom or sulfur atom. The malononitrile compound has an efficient pesticidal activity and can control effectively pests such as insect pests, acarine pests, nematode pests and the like.

- A facile method for the construction of highly substituted acetonitriles and olefins. Malononitriles as acetonitrile carbanion and alkylidene dianion equivalents
-
The use of malononitrile to facilitate the preparation of highly substituted nitriles, via reductive alkylation/addition, and olefins, via a combination of reductive addition and reductive elimination, is described.

- Phase Transfer Catalysis without Solvent: Selective Mono- or Di-alkylation of Malononitrile
-
Monoalkyl and symmetrical or unsymmetrical dialkylmalononitriles have been prepared selectively by phase transfer catalysis in the absence of solvent.Exclusive formation of a particular compound is achieved in all cases except for benzylmalononitrile 2f (79percent) and prop-2-ynylmalononitrile 2g (62percent).
