181075-89-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 181075-89-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,0,7 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 181075-89:
(8*1)+(7*8)+(6*1)+(5*0)+(4*7)+(3*5)+(2*8)+(1*9)=138
138 % 10 = 8
So 181075-89-8 is a valid CAS Registry Number.

Reactions of RSe-EMe3 (E = Si, Ge, Sn, Pb) with XeF2 - RSe-F equivalents in the fluoroselenenylation of acetylenes

Poleschner, Helmut,Heydenreich, Matthias,Schilde, Uwe

, p. 1307 - 1313 (2007/10/03)

Selenides of the type R1Se-EMe3 (E = Si, Ge, Sn, Pb) react with xenon difluoride by cleavage of the Se-E bond to yield the R1Se-F intermediate and the fluorides Me3E-F, whereas the Se-C bond in PhSe-tBu (E = C) is stable against XeF2. The presence of R1Se-F intermediates is confirmed by addition to acetylenes (4-octyne, 3-hexyne). Thus, the fluoroselenenylation of acetylenes gives fluoro(organylseleno)olefins in preparative yields. In the cases of E = Si, Ge, Sn, and Pb, aryl and n-alkyl groups are suitable as the substituent R1. The X-ray crystal structural analysis of (E)-3-(p- carboxyphenylseleno)-4-fluorohex-3-ene - the first example of an uncharged fluoroselenoolefin synthesized from p-EtO2C-C6H4-Se-SnMe3, XeF2, and 3- hexyne followed by an ester hydrolysis - shows that the addition of the selenenylfluoride intermediate to the acetylene proceeds via a trans- addition, as is known for the R2Se2-XeF2 reagents.

Fluoroselenenylation of acetylenes with xenon difluoride-diorganyl diselenides; synthesis and structure elucidation of functionalized vicinal (e)-fluoro(organylseleno)olefins

Poleschner, Helmut,Heydenreich, Matthias,Schilde, Uwe

, p. 1187 - 1193 (2007/10/03)

We carried out the fluoroselenenylation of hex-3-yne with xenon difluoride and functionalized diselenides (dimethyl acetal- and carboxylic acid ester-substituted) to the corresponding substituted vicinal (E)-fluoro(organylseleno)olefins. Consecutive react
