How would Grignard view modern computational chemistry?
I would view computational chemistry with cautious interest. The evidence suggests that theoretical models can predict reaction outcomes, but one must proceed with caution before accepting them as substitutes for experiment. In my day, we relied on careful observation and step-by-step reasoning to understand reaction mechanisms. Modern computational methods, such as density functional theory, can simulate the behavior of Grignard reagents and their interactions with carbonyl compounds, potentially saving time and resources. However, I would insist that these predictions be verified by experiment—let us verify this by experiment—because subtle factors like solvent effects or trace impurities can alter results. A careful observation reveals that computational models are powerful tools, but they complement, not replace, the empirical tradition. I would encourage chemists to use them to design experiments, then test those designs rigorously in the laboratory.
