资源简介：
The reactivity of a nucleophilic
palladium carbene, [PC(sp2)P]Pd(PMe3) (1; [PC(sp2)P] = bis[2-(diisopropylphosphino)phenyl]methylene),
toward the C–H
bonds of CH3COCH3, CH3CN, Ph–CCH,
fluorene, and 9,10-dihydroanthracene was investigated. All surveyed
substrates reacted with 1. However, there was no detectable
reaction of 1 with Ph2CH2. It is
proposed that the pKa values of the studied
C–H bonds govern their reactivity toward 1: our
results show that substrates with a pKa higher than 29, such as Ph2CH2 (pKa = 32.2), do not react even with prolonged heating.
