Relative reactivities of ±,-unsaturated carbonyl compounds toward n-butylmagnesium bromide are determined by competitive reactions with diethyl ketone. ±-Methyl group significantly suppresses the reactivity of
Rank the following in terms of their relative reactivities in an S_N2 reaction R-F, R-I, R-Br, R-Cl. a. R-F less than R- Br less than R- I less than R-Cl. b. R-F less than R-Cl less than R-Br less than R-I. c. R-I ...
Focuses on the attention the carbonyl compounds, especially aldehydes received when allylmetal regents were added to the them. Promise shown by crotylboron and tin reagents in combinations of metals and allylic groups; Diastereoselective addition reactions with the formation of contiguous stereocenters....
The gas-phase basicities and relative methylation nucleophilicities of a series of simple cyclic carbonyl-containing compounds were evaluated in order to understand the low reactivities of some barbiturates and anti-convulsants in the gas phase. The gas-phase basicities were determined by the ...
