詳細

アプリケーション

• Allene is extensively used in a variety of photochemical,[1][2] thermal,[1][3][4] and transition metal-mediated cycloadditions.[1]
• It can be lithiated to obtain allenyllithium which reacts with alkyl halides to afford terminal allenes.[5]
• Additional application includes the preparation of reagents such as isopropenylsilanes and isopropenylstannanes by reacting with stannyl and silyl cuprates respectively.[1][6]
