Purification Methods
Fractionate the stannane under reduced pressure and taking the middle fraction to remove impurities such as (n-Bu)3SnCl. [Seyferth & Stone J Am Chem Soc 79 515 1957, Beilstein 16 III 1279.]
Check Digit Verification of cas no
The CAS Registry Mumber 7486-35-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,8 and 6 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 7486-35:
(6*7)+(5*4)+(4*8)+(3*6)+(2*3)+(1*5)=123
123 % 10 = 3
So 7486-35-3 is a valid CAS Registry Number.

Stille coupling involving bulky groups feasible with gold cocatalyst

Gold shuttle: Bulky groups, which will not (or only very sluggishly) undergo Stille coupling with stannanes and inexpensive ligands, can be efficiently coupled using bimetallic catalysis. A gold cocatalyst serves as an efficient shuttle to convey the bulky group from tin to palladium by reducing the steric crowding in the transition-states (see scheme). Copyright
H NMR evidence for the formation of vinyllead triacetates. The reactions of vinylmercury, vinyltin, and vinylboronic acids with lead tetraacetate

Vinylmercury compounds, vinylboronic acids and vinylstannanes undergo rapid metal-lead exchange with lead tetraacetate in deuterochloroform to generate vinyllead triacetates, which have been characterised by their 1H-1H and 207Pb-1H coupling constants. In addition, a number of divinyl and mixed aryl-vinyllead dicarboxylates have been prepared via boron-lead exchange.
