Aliphatic compounds and derivatives

Phentolamine is a synthetic mesylate that is used as an antihypertensive agent, and for the treatment of Raynaud's syndrome and pheochromocytoma. Phentolamine is also used to prevent frostbite and to treat various types of shock. Phentolamine blocks alpha-2-adrenergic receptors, thereby decreasing sympathetic nerve impulses to the heart, blood vessels, kidneys, and other organs. This drug also acts as a histamine antagonist by blocking H1-receptors on vascular smooth muscle cells. Phentolamine has been shown to have no significant effects on 5-hydroxytryptamine (5HT) release in vitro or in vivo.

2-Bromo-3,3,3-trifluoro-1-propene is a chemical compound that has been synthesized in an asymmetric reaction. The reactant is bromopropane and the product is 2,2,2-trifluoropropene. The methylene group on the propene molecule is activated by the nucleophilic attack of a fluoride ion from hydrogen fluoride to form a cavity with a highly strained bond. The kinetic study of this reaction revealed that the activation energy for the reaction is 42 kJ/mol. Palladium-catalyzed coupling reactions are catalyzed by palladium and require nonpolar solvents such as toluene or dichloromethane. This type of reaction has been shown to be exothermic with an isolated yield of 1%.

2,2-Paracyclophane is a high-sensitivity c-reactive protein (hsCRP) that has been isolated from the fungus Cryptococcus neoformans. This compound has shown to have anti-cancer properties in animal studies. 2,2-Paracyclophane binds to fatty acids and is soluble in water, which may be due to its hydrogen bonding with the hydroxyl group at C1. The crystal structure of this compound reveals that it has a cyclohexane ring and two fatty acids. The thermal expansion coefficient of this molecule is also high, which suggests that it may be suitable for use as a solid lubricant.

1,2-Bis(chlorodimethylsilyl)ethane is a reactive chemical that is synthesized from hydroxychloroformates and hydrogen chloride. It reacts with silicon to form chlorosilanes, which are then used in the polymerization of siloxanes. 1,2-Bis(chlorodimethylsilyl)ethane has been shown to be an effective initiator for the polymerization of methyl methacrylate and ethylene glycol dimethacrylate. 1,2-Bis(chlorodimethylsilyl)ethane is also used as a hydroxyl group donor in organic reactions.
