for E–E bond cleavage (where E = S, Se) at room temperature and gives satisfactory yield of the titled compounds. Molecular structure of bis[p-chlorophenyl(phenyl)methyl] diselenide (3) and diphenylmethylseleno-2-propene 7 has been established with the help of single crystalX-ray analysis. The compound (3) is triclinic and crystallizes into P1¯ space group, whereas the compound 7 is monoclinic with P21/C
Synthesis and characterization of novel pyridyl/naphthyl/(diphenyl)methylseleno substituted alkanoic acids: X-ray structure of 2-pyridylselenoethanoic acid, 2-naphthylselenoethanoic acid and 2-(diphenyl)methylselenoethanoic acid

sodium borohydride in ethanol. The ethyl pyridyl/naphthyl/(diphenyl)methylseleno substituted alkanoates (8–13) on basic hydrolysis and subsequent acidification afford pyridyl/naphthyl/(diphenyl) methylseleno substitutedalkanoicacids (20–25) in excellent yields. These selenoalkanoates (8–13) and selenoalkanoic acids (20–25) have been characterized by elemental analysis and various spectroscopic techniques
