Phosphorus ylides, their preparation and use thereof as low-nucleophilic strong-basic compounds |
| 摘要 |
<p>The invention concerns the use of ylides of phosphorus of general formula (I') in which R'1, R'2, R'3, R'4, R'5 represent different variable groups, as a slightly nucleophilic base. The invention also concerns novel ylides of general formula (I) in which R1, R2 and R3 and R4 represent different variable groups and R5 represents a polymeric support.</p> |
