Synthesis and structure of 5,6,7,12-tetrahydrodibenz[c,f][1,5]azabismocines

Efficient Fixation of Carbon Dioxide by Hypervalent Organobismuth Oxide, Hydroxide, and Alkoxide

“…[12] As reported, the Bi À N coordination bonds in 5,6,7,12-tetrahydrodibenz[c,f][1,5]azabismocines change length in response to the electronic nature of the bismuth atom. [7,19] The BiÀN bonds in carbonates 7 (2.610(3) and 2.634(3) ) and 8 (2.548(3) ) and in carbamate 11 (2.591(2) ) are (4) ) and 9 (2.687 (2) ), and oxide 6 (average 2.747(6) ), in accordance with the expectation. In turn, BiÀO bonds in 7 (2.253(2) ), 8 (2.303(3) ), and 11 (2.278(2) ) are longer than those in 4 (2.170(4) ), 5 (2.170(4) ), 9 (2.175(2) ), and 6 (2.077(6) ).…”

Synthesis, structure, and in vitro antiproliferative activity of cyclic hypervalent organobismuth(III) chlorides and their triphenylgermylpropionate derivatives

“…The equatorial position of the other compounds is occupied by two carbon atoms with the C Ar -Bi-C Ar angle considerably diminished (less than 120°) and with the N (O, S)-Bi-X bond angle ranging from 148.5(1) to 160.6(2) Å. The Bi-N distance (2.357(2) Å) in the cationic complex [ t BuN(CH 2 C 6 H 4 ) 2 Bi] + [B(C 6 F 5 ) 4 ] À is much shorter than those of previously reported neutral 5,6,7,12-tetrahydrodibenz[c,f] [1,5]azabismocines (2.559(4)-2.894(4) Å) [7,9], and those of the newly synthesized compounds 4a,b and 5a,b (2.517(4)-2.631(4) Å).…”

“…In the past decade, there has been a rapid development on bismuth chemistry, and some novel bismuth compounds have been reported [4][5][6][7][8][9][10][11]. Over 200 years, inorganic bismuth salts have been used as medicinal drugs because of their low toxicity and high effectiveness in the treatment of a variety of microbial infections [12][13][14][15].…”
