“…In these CX 4 molecules, there are no weak inter-ligand bonding interactions, and typically (although not invariably) the X group bears one non-H substituent at the 1-position. For borates with boron attached to a Csp 3 atom, the C-B bond length is typically 1.575 Å (Wadepohl et al, 2000;Al-Masri et al, 2005;Harlow et al, 2013), but is slightly longer, 1.603 (2) Å , in the sterically crowded molecule (E)-2-(1,1-dicyclohexyl-3-phenyl-3-allyl)-5,5-dimethyl-1,3,2-dioxaborinane (El-Hiti et al, 2013). The C-B bond length in C[B(OMe) 2 ] 4 lies within this range.…”

“…150 The reaction of BEt 3 with the (2-dimethylaminophenyl)alcohols 1-HOX-2-NMe 2 C 6 H 4 (X ¼ CPh 2 , CCy 2 , CPh 2 CH 2 ) in 1 : 2 and 1 : 1 reaction ratios has been shown to produce a range of intramolecularly base stabilised {BEt 2 } and {BEt} derivatives. 151 Hypervalent, pentacoordinate and tetracoordinate compounds bearing an anthracene skeleton with two oxygen or nitrogen donor groups (OMe and NMe 2 respectively) in the 1,8-positions have been synthesised and reported. Several of the boron compounds bearing {BO 2 -1,2-C 6 H 4 } (23), {B(OMe) 2 }, {BMe 2 }, {BS 2 -1,2-C 6 H 4 }, {BF 2 } and {BCl 2 } units have been structurally characterised.…”
