TABLE 1
HSAB parameters for unsaturated aldehydes
Softness (σ) and electrophilicity (ω) for the selected compounds were calculated as described in Materials and Methods. Nonaldehydes N-acetyl-p-benzoquinoimine (NAPQI) and acrylamide are included for comparative purposes.
| Electrophile | Structure | Softness (σ × 103 ev−1) | Electrophilicity (ω, ev) |
|---|---|---|---|
| NAPQI |  | 499 | 6.83 |
| Acrolein |  | 371 | 3.82 |
| HNE |  | 377 | 3.80 |
| Crotonaldehyde |  | 367 | 3.56 |
| Malondialdehyde |  | 384 | 3.39 |
| Acrylamide |  | 315 | 2.62 |
