Treatment o f C[B(OMe)J4 with four equivalents o f a (rerr-phosphine)gold(I) chloride LAuCl with L = P (oC 6H n)3 or (2-MeC6H4)3P in the presence o f CsF in hexamethylphosphoric triamide (HMPT) affords the first complexes o f the type (LAu)4C. The product is formed to­ gether with salts (LAu)5C +BF4_ as the by-product for L = tricyclohexylphosphine, from which it can be separated by fractional ...

In this paper we study the relation between module amenability of $theta$-Lau product $A×_theta B$ and that of Banach algebras $A, B$. We also discuss module biprojectivity of $A×theta B$. As a consequent we will see that for an inverse semigroup $S$, $l^1(S)×_theta l^1(S)$ is module amenable if and only if $S$ is amenable.

in this paper we study the relation between module amenability of θ - lau product a×θb and that of banach algebras a, b. we also discuss module biprojectivity of a×θb. as a consequent we will see that for an inverse semigroup s, l 1 (s) ×θ l 1 (s) is module amenable if and only if s is amenable.
