Robinson Annulation Robinson Annulation is an useful organic reaction. This reaction is named after a British chemist Sir Robert Robinson. The term ’annulation ’stands for ’building a ring ’. In this reaction‚ the formation of α‚ β-unsaturated cyclic ketones from methl vinyl ketones and aldehyde or ketones takes place. Actually this reaction is a combination of two reactions. One is ’Michael Addition ’ and the other is ’Aldol Condensation ’. Robinson Annulation Mechanism In the first step

In the reaction mechanism‚ a carboxylic acid‚ m-toluic acid is used to synthesize N‚N-diethyl-m-toluamide‚ also know as DEET‚ through a nucleophilic acyl substitution reaction. The reaction begins by first converting the m-toluic carboxylic acid into an acyl chlorosulfite through a reaction using thionyl chloride. The carboxylic acid is converted into an acyl chloride because the acyl chloride is more reactive. In this step‚ hydrochloric acid is formed from a hydrogen on the carboxylic acid and a

Synthesis of Salicylic Acid from Wintergreen Oil Objective – Preparation of salicylic acid (organic synthesis) from methyl salicylate utilizing previously used procedure from the nineteenth century. The final product will then be evaluated in comparison to salicylic acid made from benzene. Discussion – In this synthesis‚ methyl salicylate is the starting material or precursor and salicylic acid is the target product. It is the major constituent of wintergreen oil. The difference in structures

Analysis of Hydrocarbons Jessa Grace B. Castillo* and Stephanie Chua Department of Chemistry‚ University of Santo Tomas‚ Manila‚ Philippines ______________________________________________ Hydrocarbons are organic compounds containing only hydrogen and carbons and further divided in major types. Hydrocarbons react differently in reagents. The basis of determining an unknown hydrocarbon is due to the differences in reactions of hydrocarbons. An unknown compound is determined using tests.

I. Carbonyl Compounds‚ Enols and Enolates. Some of the most suitable reactions of carbonyl compounds contain carbon hydrogen bonds adjacent to the carbonyl group. Such reactions‚ which can be observed as the strength of much synthetic organic chemistry‚ usually result in the replacement of the hydrogen by some other atom or group‚ as in the H-C-C=O -+ X-C-C=O. Transformation of a carbonyl compound to an enol at a suitable rate typically needs either a basic catalyst or an acidic catalyst and

Jeffery Kesterson Monique Babin WR-122 15 May 2015 Is Organic Food Really Healthier For You? Maya W. Paul wrote an article for Helpguide.com about organic foods geared towards helping people understand how to read organic food labels and their benefits and claims. When she wrote her definition for the word “organic”‚ she defined it as: Organic crops must be grown in safe soil‚ have no modifications‚ and must remain separate from conventional products. Farmers are not allowed to use synthetic pesticides

In “The Politics of Organic Farming: Populists‚ Evangelicals‚ and the Agriculture of the Middle”‚ author Laura Sayre begins by speaking about how the Obama administration initially acted enthusiastically towards the sustainable food movement‚ which was a PR gesture‚ when really‚ they were silently allowing the agendas of agribusiness giants to move forward (38). Sayre quotes journalist Barry Estabrook who calls this “the Obama administration’s schizophrenic approach to agriculture policy” (38).
