3.6.16.5 Cycloadditions via Gold-Coordinated Heteroatom Intermediates

DOI: 10.1055/sos-SD-103-00177

Qian, D.; Zhang, J.Science of Synthesis Knowledge Updates, (2017155.

Although gold complexes are successfully used to facilitate various cycloaddition reactions by carbophilic activation,[‌1‌‌11‌] there are fewer examples of the use of gold complexes as σ-Lewis acids to catalyze cycloadditions by coordinating to heteroatoms.[‌117‌]
