An improved method for the generation of dichlorocarbene was developed that utilizes ultrasound in the reaction of carbon tetrachloride with magnesium. High yields of gem-dichlorocyclopropane derivatives can be obtained in the presence of olefins by this method.

A three-step synthetic route to a novel water soluble phase transfer reagent, Diquat (Dq-Br), viz., 2-benzilidine-N,N,N,N',N',N'- hexaethyl propane-1,3 diammonium dibromide and its utility in various dichlorocarbenations to olefins are described.
REACTIONS OF DICHLOROCARBENE AND OF THE SIMMONS-SMITH REAGENT WITH THE DIMER AND TRIMER OF CYCLOPENTADIENE AND THE DIMER OF SPIROHEPTA-4,6-DIENE

Dichlorocarbene reacts with the exo dimer of cyclopentadiene (exo-tricyclo2,6>deca-3,8-diene) and the trimer of cyclopentadiene (exo-endo-pentacyclo2,7.09,13>pentadeca-4,10-diene) at the cyclopentene double bond.The Simmons-Smith reagent, prepared from methylene iodide in presence of a zinc-silver couple, reacts with the same hydrocarbons and also with the dimer of spirohepta-4,6-diene 2,6>deca-3,8-diene)-10-spirocyclopropane> nonselectively at both double bonds, whereas it adds to the trimer of cyclopentadiene only at the norbornene double bond.
