Silanes - Organic Chemistry Portal

Silanes serve, depending upon the type of the silane, as a radical H-donor or as a hydride donor. The range reaches from simple alkyl silanes, alkyl silicones, over different phenylsilanes and halosilanes up to tris silane, which is due to its structure an outstanding radical reducing agent.

Silanes are often used as an alternative to toxic reducing agents. But they offer their own chemistry due to the outstanding affinity from silicon to oxygen and fluorine.

A highly efficient silver-catalyzed chemoselective method enables the reduction of aldehydes to their corresponding alcohols in water by using hydrosilanes as reducing agents. Ketones remained essentially inert under the same reaction conditions.

An experimentally simple Microwave-assisted reductive alkylation of methyl carbamate with a range of aldehydes provides, after basic work-up, structurally diverse primary amines. This method is particularly amenable to high-throughput synthesis.

Drug Class And Mechanism For Alprazolam

Alprazolam is an anti-anxiety medication in the benzodiazepine family, the same family that includes ethylone,diazepam (Valium), clonazepam (Klonopin), lorazepam (Ativan), flurazepam (Dalmane), and others. Alprazolam and other benzodiazepines act by enhancing the effects of gamma-aminobutyric acid (GABA) in the brain. GABA is a neurotransmitter (a chemical that nerve cells use to communicate with each other) that inhibits activity in the brain. It is believed that excessive activity in the brain may cause anxiety or other psychiatric disorders. The FDA approved alprazolam in October 1981.

Alprazolam is used for the treatment of anxiety disorders and panic attacks. Anxiety disorders are characterized by unrealistic worry and apprehension, causing symptoms of restlessness, aches, trembling, shortness of breath, smothering sensation, palpitations, sweating, cold clammy hands, lightheadedness, flushing, exaggerated startle responses, problems concentrating, and insomnia. Panic attacks occur either unexpectedly or in certain situations (for example, driving), and can require higher dosages of alprazolam.
