TL;DR: In this paper, a model reaction of cyclodecane-r-1,c-5, c-9-triol with 2,3-dimethoxybenzoyl chloride in pyridine was described.
Abstract: Reaction of cyclododecane-r-1,c-5,c-9-triol with 2,3-dimethoxybenzoyl chloride in pyridine gave cyclododecane-r-1,c-5,c-9-triyl tris(2,3- dimethoxybenzoate), which upon treatment with 3 mol of boron tribromide at low temperature gave 83% yield of cyclododecane-r-1,c-5,c-9-triyl tris(2-hydroxy-3-methoxybenzoate). When 6.5 mol of boron tribromide was used under similar conditions cyclo-dodecane-r-1,c-5,c-9-triyl tris(2,3-dihydroxybenzoate) was obtained in 77% yield. Some model reactions of isopropyl 2,3-dimethoxybenzoate with boron tribromide are described.

TL;DR: Some dibromo(dialkylamino)boranes of composition Br2B-NR2 were synthesized by the reaction of boron tribromide with secondary amines.
Abstract: Some dibromo(dialkylamino)boranes of composition Br2B-NR2, where R = C3H7, C4H9, C5H11, C2H5 were synthesized by the reaction of boron tribromide with secondary amines.
