18906-12-2 Usage

General Description

1,1-dichloro-1,1a,1b,2,5,5a,6,6a-octahydro-2,5-methanocyclopropa[a]indene is a highly complex chemical compound. It is a bicyclic hydrocarbon that contains two chlorine atoms and several fused cyclopropane rings. The chemical structure of 1,1-dichloro-1,1a,1b,2,5,5a,6,6a-octahydro-2,5-methanocyclopropa[a]indene makes it highly stable and resistant to degradation, and it has the potential to be used as a building block in the synthesis of complex organic compounds. However, due to its intricate structure and potential reactivity, it also poses health and environmental risks, and therefore requires careful handling and management.

Check Digit Verification of cas no

The CAS Registry Mumber 18906-12-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,9,0 and 6 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 18906-12:
(7*1)+(6*8)+(5*9)+(4*0)+(3*6)+(2*1)+(1*2)=122
122 % 10 = 2
So 18906-12-2 is a valid CAS Registry Number.

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

Lin, Haixia,Yang, Mingfa,Huang, Peigang,Cao, Weiguo

, p. 608 - 613 (2003)

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 new phase transfer reagent for the addition of dichlorocarbene to olefins under mild PTC conditions

Jayachandran, J. Paul,Wang, Maw-Ling

, p. 4101 - 4112 (2007/10/03)

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

Molchanov, A. P.,Kostikov, R. R.,Chernyshev, V. A.

, p. 1444 - 1449 (2007/10/02)

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.
