Abstract New 1, 3, 6, 2-dioxazaborocanes R 1 N (CHR 3 CR 4 R 2 O)(CHR 6 CHR 5 O) BX (1–11, X= Ph, 4-MeC 6 H 4, Me; R 1= Me, PhCH 2; R 2, R 3, R 4, R 5, R 6= H, Ph) were synthesized by the reactions of aryl-or methylboronic acids with dialkanolamines. The treatment of (Me 2 NCH 2 CH 2 O) 3 B (15) with MeN (CH 2 CH 2 OH)(CH 2 CPh 2 OH) afforded 2-[2-(dime-thylamino) ethoxy]-1, 3, 6, 2-dioxazaborocane (12). 2-Fluoro-1, 3, 6, 2- ...
