Trimethylsilylacetylene is used in Sonogashira couplings as the equivalent of acetylene. Using this protected alkyne, as opposed to acetylene itself, prevents further coupling reactions. The trimethylsilyl group can then be cleaved off with TBAF or DBU, either separately or as part of a one-pot Sonogashira … See more Trimethylsilylacetylene is the organosilicon compound with the formula (CH3)3SiC2H. A colorless liquid, "tms acetylene", as it is also called, is used as a source of "HC2 " in organic synthesis. See more Trimethylsilylacetylene was first synthesized in 1959 by Heinz Günter Viehe. He reduced chloro(trimethylsilyl)acetylene by reaction with phenyllithium in diethyl ether and proceeded with subsequent hydrolysis. See more WebEtamsylate is a haemostatic agent; also promotes angioprotective and proaggregant action. It stimulates thrombopoiesis and their release from bone marrow. Haemostatic action is due to activation of thromboplastin formation on damaged sites of small blood vessels and decrease of PgI2 ( Prostacyclin) synthesis; it also facilitates platelet ...

Bis(trimethylsilyl)acetylene (BTMSA) is an organosilicon compound with the formula Me3SiC≡CSiMe3 (Me = methyl). It is a colorless liquid that is soluble in organic solvents. This compound is used as a surrogate for acetylene. BTMSA is prepared by treating acetylene with butyl lithium followed by addition of chlorotrimethylsilane:
WebJun 13, 2005 · The mechanism of action of levamisole as an antiparasitic agent appears to be tied to its agnositic activity towards the L-subtype nicotinic acetylcholine receptors in nematode muscles.
