The reaction of some bicyclic pyrazolines with alkyl halides, aryl sulphonyl chlorides as well as with some N–H and S–H containing heterocycles is affected in solid-liquid two phase systems using a catalyst. The catalytic cycle is described, the purity of the obtained products is checked using TLC and their structure is confirmed by a combination of chemical and spectroscopic methods.
