Boronic compounds
This invention relates to a diboron derivative of formula (I) or a diboron derivative of formula (II) or a diboron derivative of formula (III) where R1, R2, R3 and R4 are each independently selected from the group consisting of optionally substituted alkyl, optionally substituted alkenyl, optionally substituted aryl, optionally substituted cycloalkyl, optionally substituted cycloalkenyl, a group of the formula ?(R5Q)mR6 where Q is selected from O, S, NR7, optionally substituted arylene and optionally substituted cycloalkylene, m is an integer selected from 1 to 3, the or and each R5 is independently an optionally substituted C1-C3 alkylene, R6 is C1-C3 alkyl or hydrogen, and R7 is hydrogen or C1-C12 alkyl; each X is independently selected from O, S(O)n and NR7, where n is an integer from 0 to 3, R7 is hydrogen or C1-C12 alkyl, or one or more of ?NR1R7, ?NR2R7, ?NR3R7 and ?NR4R7 represent an optionally substituted 5 or 6 membered heterocyclyl group,and A, A1 and A2 are divalent groups which may or may not be different.
