Abstract
Способ получения 5-[(4-хлорфенил)метил]-2,2-диметилциклопентанона включает: взаимодействие метилового или этилового эфира 1-[(4-хлорфенил)метил]-3-метил-2-оксоциклопентанкарбоновой кислоты с гидридом натрия и метилгалогенидом; и гидролиз полученного метилового или этилового эфира 1-[(4-хлорфенил)метил]-3,3-диметил-2-оксоциклопентанкарбоновой кислоты. Таким способом, в соответствии с настоящим изобретением, можно получать 5-[(4-хлорфенил)метил]-2,2-диметилциклопентанон как важное промежуточное соединение для сельскохозяйственного или садового фунгицида, например, метконазола, с высоким качеством и высоким выходом.
