Equipment : Please make sure that all equipment is dry . Traces of water will destroy 4 -methoxybenzaldehyde dimethyl acetal , and the reaction will not lead to the target compound .For your set- up use a 10 ml pear shaped flask with a magnetic stirring bar and a drying tube .. Dissolve methy ! a - D- glucopyranosede ( 0. 50 mmol , 97 my ) in dimethyl sulfoxide ( DMSO ; Im[ ) .. 4 -Methoxybenzaldehyde dimethyl acetal ( a . K . a . anis aldehyde dimethyl acetal ) ( 150 ML , 0. 88mmol ) is added next with the help of an adjustable pipette .*. Finally , the reaction is started by the addition of camphor - 10 - sulfonic acid ( 0 . 13 mmol , 30my ) .. Cover the flask with a loose stopper , and stir the mixture at room temperature for I hr .". Add three drops of triethylamine from a Pasteur pipette to stop the reaction .". Add 2. 5 mL of water to the reaction mixture . The product will precipitate within 10 minutes .. Filter the reaction mixture , and wash the solid product with water .". Purify the product by recrystallization from a very small amount of isopropanol .. Develop a TLC of the recrystallized product in pure ethyl acetate .". After drying , each group should submit one sample for HI - NMR analysis .. Determine the yield ( in & and % ) of the product after recrystallization .*. Store the product for future experiments in a screw cap vial .2 nd day in the lab : Depending on the outcome of the first lab session , we may modify and repeatour synthesis , or we may work on the purification of our product .. In your lab report , please answer the following questions :"a) In our reaction , which factors create conditions favorable for an S'N'I mechanism , whichfactor ( s ) suggest that the mechanism might prefer an SN 2 mechanism ?!
