SYNTHESIS AND SPECTROSCOPIC PROPERTIES OF MIXED GLYCOLATE-SALICYLALDIM INATE DERIVATIVES OF ARSENIC(III)

Abstract

Mixed glycolate-salicylaldiminate derivatives of arsenic(III) of the type OC₆H₄CH˭NAr have been prepared by the reactions of equimolar amounts of Cl [G=CH₂CH₂ (G¹), CHMeCHMe (G²), CMe₂CMe₂ (G³), CHMeCH₂CMe₂ (G⁴), CMe₂CH₂CH₂CMe₂ (G⁵)] with N-arylsalicylaldimines (HOC₆H₄CH˭NC₆H₅ (HL¹), HOC₆H₄H₄CH˭NC₆H₃Me₂-2,6 (HL²), HOC₆H₄CH˭NC₆H₃Et₂-2,6 (HL³) and HOC₆H₄CH˭NC₆H₃(Pr-i)₂-2,6 (HL⁴); in benzene using Et₃N as a proton acceptor. These new derivatives have been characterized by elemental analyses, molecular weight measurements and spectroscopic [IR, NMR (¹H and ¹³C)] studies.
