Functionalisation of siloles

Japanese researchers have synthesised 3-allyl-1-silaindenes by gold-catalysed intramolecular trans-allylsilylation reaction of alkynes. Masahiro Murakami and colleagues at Kyoto University are interested in the synthesis of silole derivatives which possess unique photophysical and electronic properties. They have now developed a method to synthesise 3-allyl-1-silaindenes from alkynes having an allylsilane moiety by a gold-catalysed intramolecular trans-allylsilylation reaction. Benzosilole derivatives having various functional groups at the 2-position were synthesised.
Siloes have promising potential for electronic devices and synthetic methods that allow various functional groups to be added are sought. Future directions will be in the 'development of silicon-based electronic materials' and 'chemistry of gold-catalyzed reactions of alkynes,' said Murakami.
