12155-17-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 12155-17-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,1,5 and 5 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 12155-17:
(7*1)+(6*2)+(5*1)+(4*5)+(3*5)+(2*1)+(1*7)=68
68 % 10 = 8
So 12155-17-8 is a valid CAS Registry Number.

Regioselective Nucleophilic Additions to Tricarbonyl(η6-arene)chromium(0) complexes: Electronic versus Chelation Control

Blagg, Julian,Davies, Stephen G.,Goodfellow, Craig L.,Sutton, Kevin H.

, p. 1133 - 1144 (2007/10/02)

Regioselective addition of t-butyl-lithium to tricarbonyl(η6-benzyl alcohol)chromium(0) proceeds to give tricarbonyl(η6-5-methylene-6-exo-t-butylcyclohexa-1,3-diene)chromium(0), which can be isomerised to tricarbonyl(η6-o-

Tricarbonylchromium Complexes of Aryltrimethylsilanes - Synthesis and Reactions

Effenberger, Franz,Schoellkopf, Klaus

, p. 4356 - 4376 (2007/10/02)

Tricarbonylchromium (TCC) complexes 3, 12 of aryltrimethylsilanes are synthesized by reaction of aryltrimethylsilanes 2 and phenylenebis(trimethylsilanes) 11, resp., with hexacarbonylchrom (1).Under basic catalysis 3 and 12 react - caused by the acceptor effect of the tricarbonylchromium (TCC) group - with aldehydes and ketones to give the TCC-alkyl(trimethylsilyl) ether complexes 4, 9, 13.Hydrolysis of 4, 13 accomplish TCC complexes 5 of substituted benzyl alcohols.The oxidative removal of the TCC group with iodine or sodium dichromate was demonstrated with 4a yieldi ng benzhydrol (7) and benzophenone (8f), respectively.Nucleophiles can be added to the aromatic ring of 4, 9, 13 by known methods; the TCC complexes 3, 12, therefore, can be used for the straightforward synthesis of multiply substituted arenes by combination of electrophilic carbodesilylation and nucleophilic addition.
