Acetic acid, trichloro-, 1-phenylethenyl ester, also known as 1-phenylethenyl trichloroacetate, is an organic compound with the chemical formula C10H9Cl3O2. It is a colorless to pale yellow liquid with a fruity odor. This ester is formed by the reaction of trichloroacetic acid with 1-phenylethenol (also known as styrene oxide). It is used as a chemical intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals. Due to its reactivity and potential toxicity, it is important to handle Acetic acid, trichloro-, 1-phenylethenyl ester with care and in accordance with proper safety protocols.

884-08-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 884-08-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,8 and 4 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 884-08:
(5*8)+(4*8)+(3*4)+(2*0)+(1*8)=92
92 % 10 = 2
So 884-08-2 is a valid CAS Registry Number.

Selective dimerisation and addition of carboxylic acids to terminal alkynes, catalysed by thermolysed Grubbs' catalyst: A novel synthesis of enynes and vinyl esters

Melis, Karen,Opstal, Tom,Verpoort, Francis

, p. 3779 - 3784 (2007/10/03)

The transformation of triple bonds of terminal alkynes was carried out at 110 °C in the presence of the thermolysed RuII-alkylidene [Cl2(PCy3)2Ru=CHPh]. The transformation of phenylacetylene is strongly pKa-dependent, the preference switching from vinylation to dimerisation at increasing pKa values. Aliphatic alkynes only give rise to vinylation adducts, with a regioselectivity for Markovnikov addition. Wiley-VCH Verlag GmbH, 69451 Weinheim, Germany, 2002.

Mecanisme d'acetolyse d'esters d'enol styreniques

Montheard, Jean-Pierre,Camps, Marcel,Chatzopoulos, Michel,Benzaid, Ahmed

, p. 109 - 116 (2007/10/02)

We have studied the reaction of enol esters in acidic media: wherein Z = H, CH3, CH2Cl, CHCl2 and CCl3.The raction is first order.Log kex = α H'0 + β (H'0 = acidity function of Hammett) with α-1.A general acid catalysis is observed.Following a discussion of possible SN, AAC2 and ASE2 mechanisms, we propose an ASE2 mechanism for this reaction.
