The chemical compound "Zr(CH2C(CH3)3)2Cl2(CH3CH2OCH2CH3)2" is a zirconium-based organometallic complex. It features a central zirconium atom, which is bonded to two cyclopentadienyl groups (C5H5), each with a methyl group (CH3) attached to the carbon atom adjacent to the zirconium. Additionally, the zirconium is bonded to two chloride ions (Cl-) and two ethoxyethoxy groups (CH3CH2OCH2CH3). Zr(CH2C(CH3)3)2Cl2(CH3CH2OCH2CH3)2 is known for its potential applications in catalysis, particularly in olefin polymerization, due to its ability to form active catalysts when activated with appropriate cocatalysts. The structure of the compound allows for a variety of steric and electronic effects, which can influence its reactivity and selectivity in various chemical transformations.

Check Digit Verification of cas no

The CAS Registry Mumber 78068-02-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,0,6 and 8 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 78068-02:
(7*7)+(6*8)+(5*0)+(4*6)+(3*8)+(2*0)+(1*2)=147
147 % 10 = 7
So 78068-02-7 is a valid CAS Registry Number.

ATTEMPTS TO PREPARE ALKYLIDENE ZIRCONIUM COMPLEXES BY α-HYDROGEN ATOM ABSTRACTION

Wengrovius, Jeffrey H.,Schrock, Richard R.

, p. 319 - 328 (2007/10/02)

We prepared several new neopentyl halide complexes of zirconium in order to test whether they could be induced to lose neopentane and give neopentylidene complexes by adding phosphorus or nitrogen donor ligands.ZrNp2X2 (X=Cl or Br) can be prepared in ether and isolated as a dietherate (an oil).It reacts with L (L=PMe3, PMe2Ph, NEt3, 1/2 DMPE, 1/2 TMEDA) to give ZrNp2X2L2.ZrNp3Cl can be prepared by adding MgNp2 to ZrNp2Cl2(ether)2 and isolated by sublimation in 25percent yield.On adding PMe3 or TMEDA, it disproportionates to ZrNp4 and ZrNp2Cl2L2.ZrCp''NpCl2 (Cp''=η5-C5Me5), ZrCp''Np2Cl, and ZrCp''Np3 were prepared by adding MgNp2 to ZrCp''Cl3.Only the last is a solid, only the first forms an adduct, ZrCp''NpCl2(PMe3).None of the complexes decomposed to tractable products in the presence of L.Photolysis of ZrNp2Cl2(PMe3)2 yielded 2 by an apparently complex reaction initiated by homolytic Zr-Np bond fission.
