文摘
A new and efficient method for palladium(II) catalytic desulfitative conjugate addition of arylsulfinic acids with 伪,尾-unsaturated carbonyl compound has been developed. The key reacting intermediates including aryl Pd(II) sulfinic intermediate, aryl Pd(II), and C鈺怬鈥擯d complexes were captured by ESI-MS/MS, which provide new experimental evidence for the understanding of addition mechanism.
