An environmentally friendlier approach-ionic liquid catalysed, water promoted and grinding induced synthesis of highly functionalised pyrazole derivatives

Grinding induced synthesis of highly functionalised pyrazoles derivatives by use of malanonitrile, phenyl hydrazine and diversified aldehyde. Ionic liquid is used as a catalyst with water, and no by-products form. A high yield is obtained and simple handling are the benefits of the adopted route, and this route fulfils all shades of green chemistry.
