16812-43-4 Usage
General Description
Trimethyl-(trimethylstannylmethyl)stannane is an organotin compound that consists of three methyl groups attached to a central carbon atom, which is in turn bonded to a tin atom. trimethyl-(trimethylstannylmethyl)stannane is commonly used as a precursor in organic synthesis reactions, particularly in the formation of carbon-carbon bonds. Due to its high reactivity and ability to undergo various transformations, trimethyl-(trimethylstannylmethyl)stannane is valued as a versatile building block in the pharmaceutical and agrochemical industries. However, it is important to handle this substance with care, as organotin compounds are known to be toxic and have potential environmental hazards.
Check Digit Verification of cas no
The CAS Registry Mumber 16812-43-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,8,1 and 2 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 16812-43:
(7*1)+(6*6)+(5*8)+(4*1)+(3*2)+(2*4)+(1*3)=104
104 % 10 = 4
So 16812-43-4 is a valid CAS Registry Number.

The addition of tin-tin bonds to stannyl alkynes to generate 1,1,2-tristannylalkenes occurs readily in the presence of the catalyst system palladium bis(dibenzylideneacetone)/triethyl phosphite.
SOME REACTIONS OF TRIS(TRIMETHYLSTANNYL)-AND TETRAKIS(TRIMETHYLSTANNYL)-METHANE
Hawker, Darryl W.,Wells, Peter R.
, p. 37 - 44 (2007/10/02)
With a variety of electrophilic reagents reaction occurs exclusively at the CH3-Sn bonds of 4C and 3CH.While the inner Sn-C bonds remain intact, methyl groups may be progressively cleaved off, one from each of the trimethylstannyl groups; in the case of bromine a second Me group may be cleaved from each of the SnMe2Br groups.The various products were identified by 1H, 13C and 119Sn MNR spectroscopy.
