Boron Analogue of Vinylidene Dication Supported by Phosphines.
In the presence of a catalytic amount of heavier tetrylene dichlorides, an allenic diborene 1 undergoes a 1,3-hydrogen shift to afford a terminal diborene 2, which can be deemed a boron analogue of vinylidene dication stabilized by Lewis bases. X-ray diffraction analysis and computational studies re...

X-ray diffraction analysis and computational studies revealed that 2 involves a conjugative interaction between the C= C and B=B π-orbitals. The reaction of 2 with ZnBr[sub 2]afforded the corresponding isolable complex 3, in which two boon centers coordinate to the Zn atom asymmetrically. pubtype: Academic Journal doctype: Article src: R language: English refInfo: copyright: @attributes: flag: Y dt: @attributes: year: 2018 holdings: @attributes: islocal: N |
