Synthesis and characterization of some new coordination compounds of boron with mixed azines

Abstract

Some new boron complexes have been synthesized by the reaction of triisopropohxyborane with the mixed azines, prepared by the condensation of salicylaldehyde and hydrazine with aldehydes/ketones in a 1:1:1 mole ratio to give a new series of (OPr i ) 2 B(NO) type of complexes. Their structures were confirmed on the basis of elemental analyses, ultraviolet, infrared, 1 H-NMR and 11 B-NMR spectral studies. The ligands and their boron complexes were also screened for their antifungal activity. Several of these complexes were found to be quite active in this respect.

Effect of trace elements Zn, B, Mg and Cu on the growth and sporulation of Pyricularia oryzae, the causal organism of blast disease of rice

“…Cresswell et al [19] have reported that Boron was more inhibitory than Cu to mycelia growth of Agaricus biosporus. The radial growth of pathogenic fungi Pyricularia oryzae, Fusarium oxysporum and Aspergillus niger was reduced by the activity of Boron [20]. Chowdhury [21] observed that the use of Boron reduced the growth of Macrophomina phaseolina.…”

Structure, synthesis and application of azines: a historical perspective

“…The use of azines as starting materials in organic synthesis is well documented. 31 These readily available compounds have been widely used as substrates in the synthesis of substituted hydrazones 62 and heterocyclic compounds 37 such as pyrazoles, purines, and pyrimidines. [63][64][65][66] As dipolarophils, they can undergo 1,3-cycloadditions and thus provide an efficient route to afford 1,5-diazabicyclo[3.3.0]octanes by crisscross addition.…”

Investigation of aggregation induced emission in 4-hydroxy-3-methoxybenzaldehyde azine and polyazine towards application in (opto) electronics: synthesis, characterization, photophysical and electrical properties

“…The AIE (E) characteristics have been a great potential for the development of distinct optical applications, from sensing to light emitting devices. [ 12 ] Besides, AIE azines are having fascinating physical and chemical properties, azines and their derivatives have been extensively used in dyes,[ 13 ] biological,[ 14 ] pharmaceutical,[ 15 ] nonlinear optical fluorophores,[ 16, 17 ] design of liquid crystals,[ 18 ] as ligands for the synthesis of novel organometallic compounds [ 19 ] and other material applications.
