Abstract

In the mol­ecular structure of the title compound, C27H40N3BBr2, the B atom is connected to two bromide substituents and a guanidinate scaffold, forming a four–membered ring. An aryl group is connected to each N atom in the ring that contains two isopropyl groups in positions 2 and 6.

Comment

The title compound is a new congener of a boron amidinate and was prepared by an insertion reaction of bis(2,6-diisopropylphenyl)carbodiimide into the B—N bond of 1,1-dibromo-N,N-dimethylboramine.

Findlater et al. (2006) reported the first example of the insertion of a carbodiimide into a boron–nitrogen bond to generate [(Me3Si)2NC{NCy}2]BCl2 that has a boron–halide bond. Before this, their preparation was only known via salt metathesis reactions of the appropriate lithium amidinates with haloboranes.

As shown in Fig. 1, the B—Br distances and the B—N distances are comparable with those found in [(Me3Si)2NC{NCy}2]BCl2 (Findlater et al., 2006). The angles Br1—B1—Br2 and N1—B1—N3 are smaller than the corresponding angles in [(Me3Si)2NC{NCy}2]BCl2 (Findlater et al., 2006). This could be due to the higher steric hindrance of the substituted aryl group than the cyclohexyl group in the reference substance.

Experimental

To prepare the title compound, bis(2,6-diiso-propylphenyl)carbodiimide (0.50 g, 1.38 mmol) dissolved in 2 ml toluene, and 1,1-dibromo-N,N-dimethylaminoborane (0.23 g, 1.08 mmol) dissolved in 2 ml toluene were combined and stirred for 20 h at ambient temperature. After a few minutes a precipitate was noticed. All volatiles were removed under reduced pressure. Recrystallization at ambient temperature from benzene gave colourless crystals of title compound (0.51 g, 0.88 mmol, yield 81%).

Refinement

The H atoms were placed at idealized positions and treated as riding atoms with C—H = 0.96 Å (CH3), 0.98 Å (aliphatic CH) and 0.93 Å (aromatic CH). Uiso(H) values were fixed at 1.5 times (for primary H atoms) and 1.2 times (tertiary or aromatic H atoms) Ueq of the attached C atoms.

Special details

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'s involving l.s. planes.
Refinement. Refinement of F2 against ALL reflections. The weighted R–factor wR and goodness of fit S are based on F2, conventional R–factors R are based on F, with F set to zero for negative F2. The threshold expression of\ F2 > σ(F2) is used only for calculating R–factors(gt) etc. and is not relevant to the choice of reflections for refinement. R–factors based on F2 are statistically about twice as large as those based on F, and R–factors based on ALL data will be even larger.
