Synthesis and crystal structure of 5-allyl 5Hdibenzo [b,f]azepine

Abstract

The crystals 5H-dibenzo[b,f]azepine 2 and 5-allyl-5H-dibenzo[b,f]azepine 3 were synthesized and characterized by X-ray crystallography. The compound 3 is a novel synthon for the construction of unusual isoxazoli(ne)dine rings bearing at the 5th position of dibenzo[b,f]azepine moiety. The compound 2 (C14H11N) crystallizes in the orthorhombic space group P212121 with the parameters a = 6.036(1) Å, b = 8.250(7) Å, c = 20.528(4) Å, Z = 4 and the final R factor is R1 = 0.0544. The compound 3 (C17H15N) crystallizes in the Hexagonal space group P61 with the parameters a = 11.043(9) Å, c = 18.575 Å, Z = 6 and the final R factor is R1 = 0.0373
