Effect of chlorinated polyethylene(cPE) on the morphology and mechanical properties of isotactic polypropylene(iPP) and nitrile rubber(NBR) blends was investigated. It was found that incorporation of a small amounts of cPE leads to a decrease in domain size of the dispersed phase, and uniform distribution of the dispersed phase in the blends. The PP/NBR/cPE ternary blends showed an improved tensile and tear strength as well as elongation-at-break as compared to binary PP/NBR blends. From the results on morphology and mechanical properties, optimum amount of the cPE is 5-10 wt% with repect to NBR in the blend.

Sodium periodate ($NaIO_4$) and potassium iodide (KI) in aqueous ammonia has been used for the one-pot synthesis of nitriles from the corresponding aldehydes and alcohols in moderate to good yield. This transformation, proceeds via an in situ oxidation- imination-aldimine oxidation sequence.

Thermal and photoinduced silylallylation reactions of organic halides with 3-stannyl-2-(silylmethyl)propene are explored. Silylallylations occur in moderate to high yields, producing various functionalized allylsilane products in which halide carbon is bonded to the terminal alkenic carbon of allylsilane with the removal of tributyltin group. The reactions, which tolerate functional groups such as carbonyl, ester, nitrile, acetal, and ketal, hold synthetic potential for the construction of functionalized allylsilanes.

Arenealdehyde 2-benzothiazolylhydrazone in thianthrene cation radicalafforded triazolo[3,4-b]benzothiazoles and 1,2,4-triazoles as major and minor product, respectively. On the contrary the similar reaction in tris(2,4-dibromophenyl)aminium hexachloroantimonate gave 1,2,4-triazoles and triazolo[3,4-b]benzothiazoles as ma-jor and minor product, respectively.
