<p>The invention relates to a process for the synthesis of organo-oxazaborolidines of the structural formula
wherein
R 4 to R 8 is hydrogen, C 1 -C 20 alkyl, C 6 -C 14 aryl, C 7 -C 24 aralkyl, C 7 -C 24 alkaryl, substituted C 1 -C 20 alkyl
or the two groups R 4 and R 5 together are a divalent group selected from the group consisting of -CH 2 CH 2 -, -CH(CH 3 )CH 2 -, -CH 2 CH 2 CH 2 -, -CH(CH 3 )CH(CH 3 )-, -CH(CH 2 CH 3 )CH 2 -, -C(CH 3 ) 2 C(CH 3 ) 2 -, -CH 2 C(CH 3 )2CH2- to form with the -NH-CR 6 - moiety a cyclic structure.</p> |
