2- ethano

The cyclobutane rings of 1,2-ethano[2.n]cyclophanes can be opened in a Birch reduction at — 60°C in tetrahydrofuran and liquid ammonia to give [4.n]cyclophanes.212-214 In this manner, macrocyclic rings with twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen and twenty-seven members have been synthesized. 

The potentially six-coordinate ligands (edta)4- and (pdta)4" (H4edta = N,N,N, N tetrakis(2-ethanoic acid)-l,2-diaminoethane, H4pdta = N,N,N, iV -tetrakis(2-ethanoic acid)-1,2-diaminopropane) add to dimeric molybdenum(V) centres to form complexes such as [Mo202Y2(edta)]2- and [Mo02Y2(pdta)]2- (Y = O, S) 425-429 The structure of... 

Ethanoate ion (1M) in ethanoic acid with 1-chloro-2-butene gives a mixture of about 85% 2-butenyl ethanoate and 15% 1-methyl-2-propenyl ethanoate. About 36% of the overall reaction product results from a process that is zero order in ethanoate ion, whereas 64% comes from a process that is first order in ethanoate ion.

Ethanoic Acetic 16.7 Esterified to glycerol in ruminant milk fats, some plant triacylglycerols and as alcohol acetates in many plants. As a component of platelet-activating factor. 

Ethano-o-carborane is a white solid, which survives unchanged after heating at 350°C for 24 h. This four-membered carbon ring compound is remarkably stable and chemically inert. It remains untouched when treated with JV-bromosuccinimide, LiN(SiMej), Brj, or DDQ. The boron cage can be chlorinated with AlOs/CCU. ...
