WebWe’re also going to be making HBr as a co-product which we don’t really care about. Let’s look at the mechanism of this reaction. The very first step is going to be the protonation of our carbonyl compound with our acidic catalyst. We need this step to convert our ketone into a corresponding enol species. Web2CH=CH2)3 and 5.9 mmol of MeLi (3.7 ml, 1.6 M solution in Et2O) in 50 ml of THF. After the lithiation of HC(SiMe2CH=CH2)3 was complete, a solution of HC(SiMe2Br)3 (803 mg, 1.88 mmol) in 50 ml of THF was transferred drop-wise via a canula at 60 oC to the Schlenk flask containing the orange solution of LiC(SiMe 2CH=CH2)3-THF complex.
