Insertion of arynes into the carbon–oxygen double bond of amides and its application into the sequential reactions
摘要:
The reaction of arynes, generated from ortho-(trimethylsilyl)aryl triflates, with the C=O bond of formamides gave salicylaldehyde derivatives via the formation of formal [2+2] adducts. The sequential transformation of arynes into ortho-disubstituted arenes, o-aminoalkylphenols or o-hydroxyalkylphenols, was achieved by one-pot procedure using dialkylzincs. (C) 2011 Elsevier Ltd.

Film-forming materials include nonionic metal coordinating structures. Nonionic metal coordinating structures can coordinate metals, such as metal catalysts and metal substrates. Example film-forming materials can be the product of a poly-functional epoxide and a nucleophilic ligand having a nonionic metal coordinating structure, or the product of a poly-functional alcohol and an electrophilic ligand having a nonionic metal coordinating structure.
