A subduction zone is also generated when two oceanic plates collide â the older plate is forced under the younger one â and it leads to the formation of chains of volcanic islands known as island arcs. Examples include the Mariana Islands in the western Pacific Ocean and the Aleutian Islands, off the coast of Alaska.
Gabriel Synthesis. Gabriel Synthesis is an organic chemical reaction in which primary alkyl halides are transformed into primary amines using potassium phthalimide. This reaction is named after a German chemist Siegmund Gabriel.Pure primary aliphatic amines are prepared from alkyl halides by this method.abriel Synthesis.

NADPH is reduced NADP (Nicotinamide adenine dinucleotide phosphate) and is used as a reducing agent. NADPH oxidises to form NADP.In plants, NADP is reduced in the last step of the electron chain of the light reactions of photosynthesis.The NADPH produced is then used as a reducing agent in the Calvin cycle of photosynthesis.ADPH is used in catabolic and anabolic reactions within the cell. Reduction and oxidation reactions occur and NADPH is used to dispose of excess reducing equivalents such as â¦ electrons. A major source of NADPH is the pentose phosphate pathway. The action of NADPH aids against ROS.
