Lab 1: Alkene Addition: Bromination of (E)-stilbene I. Introduction: 1. The purpose of the experiment was to perform an electrophilic addition reaction by using pyridinium tribromide to brominate (E)-stilbene and to identify whether it formed the meso- or racemic product through melting point analysis. 2. This is the mechanism for the bromination of (E)-stilbene. However‚ this is the mechanism for Br2 and in class we us Pyridinium Tribromide instead due to the difficulties associated

Old Dominion University ORGANIC 214 Alkene Addition Submitted by: Alkene addition: Bromination of (E) Stilbene Introduction: In this lab we used the greener approach‚ which involves the addition of bromine across a double bond. When bromine reacts with E-stilbene (trans-1‚2-diphenylethene)‚ two new chiral carbons are created from the sp2 carbons‚ therefore 3 different dibrominated stereoisomers are possible: meso-(1R‚2S)‚ or the raceminc mixture-(1R‚2R) or (1S‚2S)-dibromo-1‚2-diphenylethane

The Michael addition is a reaction named after Arthur Michael. Discovered in 1887‚ this is a carbon-carbon bond making reaction. The result of the Michael addition is a 1‚4 addition of a nucleophile to an alpha‚ beta-unsaturated carbonyl carbon compound. A 1‚4 addition is also commonly referred to as a conjugated addition. Another result of this reaction is a 1‚2 addition of a nucleophile. Some of the common attacking nucleophiles used in this reaction are enolates. Enolates‚ a negatively charged

Paper 1 Abstract: • statistically significant shifts toward the extremes of the scales • (a) that group judgments are less extreme than individual judgments‚ and • (b) that the "risky shift" phenomenon is a content-bound exception to the averaging tendency of the group. • suggests that a normative commitment may be the underlying variable responsible for polarization effects.

Bromination of Trans-Cinnamic Acid Christopher B. Martin CHEM 3411 1 Mechanism of Bromine Addition to Alkenes Understanding the chemical mechanism (order of bonds broken and made as well as intermediates formed) has a great value in chemical synthesis. The chemical mechanism of a reaction will influence the rate of the reaction‚ the stereochemistry of the product(s)‚ and the extent of possible undesired side reactions. Organic reaction mechanisms investigate the path towards a desired product
