资源简介：
Starting from 1,4- and 1,3-diborylated benzene derivatives, bitopic bis(1-pyrazolyl)borates
(K2[1,4-(tBuBpz2)2C6H4]; (Li,K)2[1,3-(tBuBpz2)2C6H4]) and tris(1-pyrazolyl)borates (K2[1,4-(Bpz3)2C6H4]) have been synthesized (pz = pyrazolyl). X-ray single-crystal structure analyses
revealed K2[1,3-(tBuBpz2)2C6H4] to establish a polymeric structure in the solid state. In
contrast, the unsymmetrically substituted hydrolysis product Li2[1,3-(tBuBpz2)(tBuB(OH)pz)C6H4] forms discrete dimers in which four lithium cations are encapsulated by their organic
ligands. As a representative of bitopic 1,2-diboryl benzene-based scorpionates, the 9,10-dihydro-9,10-diboraanthracene derivative K2[(Bpz2)2(C6H4)2] is described, which bears two
pyrazolyl substituents at each of its boron atoms and stands out due to its stereorigidity.
