Title:
BISSILYLATED 1-HYDROXYCYCLOPROPANE CARBOXYLIC ACIDS, MANUFACTURE AND USE AS INTERMEDIATE PRODUCTS
Document Type and Number:
Japanese Patent JPS57158793
Kind Code:
A
Abstract:
A bissilylated 1-hydroxycyclopropanecarboxylic acid of the formula in which R1, R2, R3 and R4 each independently is a hydrogen atom or an alkyl radical, and additionally R2 and R3 can together form a 3- to 5-membered carbon bridge, and R5, R6 and R7 each independently is an alkyl radical, is produced by oxidizing with oxygen a cyclobutene-1,2-diol-bis-trialkyl-silyl ether of the formula The products, without isolation, may directly be hydrolyzed to remove the silyl radicals and form known intermediates for further reaction.
