Abstract
The title compound, (Z)-1,2-bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1,2-bis(4-methoxyphenyl)ethene, C 28 H 38 B 2 O 6 , has a cis arrangement of two boronate ester substituents and two 4-methoxyphenyl substituents on its central C=C double bond, which shows a slight twist of ca 8.5°. All four substituents are rotated considerably out of the alkene plane to reduce steric hindrance. The BO 2 C 2 five-membered rings have a twist conformation.
