156020-87-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 156020-87-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,0,2 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 156020-87:
(8*1)+(7*5)+(6*6)+(5*0)+(4*2)+(3*0)+(2*8)+(1*7)=110
110 % 10 = 0
So 156020-87-0 is a valid CAS Registry Number.

Boron-substituted difluorocyclopropanes: New building blocks of gem-difluorocyclopropanes

Fujioka, Yasutaka,Amii, Hideki

supporting information; experimental part, p. 769 - 772 (2009/04/06)

Cycloaddition of difluorocarbene to alkenyl boronates 3 gave boron-substituted gem-difluorocyclopropanes 2 in stereospecific fashion. Upon treatment with lithium carbenoids, cyclopropyl boronates 2 underwent one-carbon homologation to afford a variety of gem-difluorocyclopropanes in good yields.

Thermal Rearrangement of N-Arylmethyl- and N-Alkyl-2,2-dihalogenocyclopropyl Imines

Kagabu, Shinzo,Ando, Chihaya,Ando, Junko

, p. 739 - 752 (2007/10/02)

An extended study of the thermal isomerization of 1-substituted 2,2-dihalogenocyclopropyl imines is reported.The thermolysis of N-arylmethyl-2,2-dichlorocyclopropanecarbaldimines 15a-h produces 2-aryl- 16a-h and 2-aryl-4-chloro-pyridine derivatives 17a-h, while N-cyclopropyl imines 15i, j yielded N-alyklchloropyrroles.The 2,2-dibromocyclopropane analogue undergoes thermolysis at lower temperatures.An ionic mechanism triggered by the halide ion dissociation is proposed for the thermal rearrangement on the basis of a study using deuterated imine 15m, and the effects of additives and solvents.On the other hand, difluorocyclopropyl imine undergoes a homolytic cleavage of cyclopropane 1,3-bond with lower activation energy than the dichlorocyclopropyl imine, and afforded the N-alykl-3-fluoropyrrole derivative preferentially.
