126086-72-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 126086-72-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,0,8 and 6 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 126086-72:
(8*1)+(7*2)+(6*6)+(5*0)+(4*8)+(3*6)+(2*7)+(1*2)=124
124 % 10 = 4
So 126086-72-4 is a valid CAS Registry Number.

Palladium-catalyzed monoamination of dihalogenated benzenes

Larsen, Simon Birks?,Bang-Andersen, Benny,Johansen, Tommy N?rskov,J?rgensen, Morten

, p. 2938 - 2950 (2008/09/19)

The palladium-catalyzed monoamination of symmetric dibromobenzenes can be performed using a catalyst based on Pd2dba3 and BINAP in the presence of NaO(t-Bu). The analogous transformation of non-symmetric bromoiodobenzenes is most effectively performed with Xantphos as the ligand, while reactions with BINAP were non-selective. These transformations can be scaled uneventfully to >10 g quantities. They do not require drybox or Schlenk techniques, and all reagents are weighed out in air. The resulting monobromoanilines are versatile intermediates for further synthetic transformations.
