Abstract: The –SO3H functionalized silica and alumina have emerged as efficient and eco-compatible heterogeneous solid acid catalysts for the construction of various important molecular skeletons. The advantages of –SO3H functionalized...
The highly electrophilic fluorosulfoxonium cation [Ph2S(O)F]+[B(C6F5)4)]- is shown to promote (n+2) annulation on Donor-Acceptor (D-A) strained cycles. This study highlights new reactions catalysed by highly electrophilic sulfoxonium cations and the...
