55453-09-3 Usage

Purification Methods

Dissolve it in Et2O, wash it with aqueous NaHCO3, H2O, 0.1M HCl, H2O again, dry (MgSO4), evaporate and distil it. [Emde & Simchen Synthesis 867 1977, Oppolzer et al. Tetrahedron 39 3695 1983, Crimmin et al. J Chem Soc Perkin Trans 1 541 1985.]

Check Digit Verification of cas no

The CAS Registry Mumber 55453-09-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,4,5 and 3 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 55453-09:
(7*5)+(6*5)+(5*4)+(4*5)+(3*3)+(2*0)+(1*9)=123
123 % 10 = 3
So 55453-09-3 is a valid CAS Registry Number.

Mukaiyama Aldol Reactions Catalyzed by Zirconocene Bis(triflate) Complexes: Stereochemistry and Mechanisms for C-C Bond Formation

Lin, Shuqiong,Bondar, Georgiy V.,Levy, Christopher J.,Collins, Scott

, p. 1885 - 1892 (2007/10/03)

The aldol condensations of α- and β-(benzyloxy) aldehydes with enol silanes, catalyzed by Cp2Zr(OTf)2THF or Cp2Zr(OTf)2, in a variety of solvents were studied. The simple diastereoselectivity of these reactions is modest and comparable to that observed using simple aldehydes of similar steric requirements. Studies have revealed that TMSOTf is directly produced on reaction with the zirconocene catalyst with the enol silane in nitroalkane solvent or is formed during catalysis in dichloromethane solution. Although TMSOTf is known to catalyze cross-aldol reactions under these conditions, the rate of this process is not always competitive with that observed using the zirconocene catalysts. In particular, sterically unhindered or aromatic aldehydes react via a mechanism that appears to be mainly Zr-catalyzed, based on both the difference in rate between Zr- and Si-mediated reactions as well as differences in enol silane/silyl triflate reactivity in crossover-type experiments. With sterically hindered aldehydes in dichloromethane or nitromethane, catalysis is mediated by Si. The Zr-catalyzed process occurs via formation of a Zr-aldolate complex from aldehyde and enol silane, with liberation of TMSOTf, followed by rate-limiting O-silylation of the metal aldolate by TMSOTf, as revealed by both model studies and in situ monitoring during catalysis.
