- A facile procedure for the generation of dichlorocarbene from the reaction of carbon tetrachloride and magnesium using ultrasonic irradiation
-
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.

- 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.

- REACTION OF DICHLOROCARBENE WITH TRICYCLO2,6>DECA-3,8-DIENE
-
Phase-catalyzed reaction of dichlorocarbene with tricyclo2,6>deca-3,8-diene gives either a mono- or a diadduct, depending on reactant proportions.The first dichlorocarbene adds to form a dichlorocyclopropane moiety, and addition of the second is accompanied by rearrangement with enlargement of the norbornane ring to give a mixture of approximately equal amounts of two isomers which differ in the position of the double bond.
