Strained hydrocarbons constitute one of the most prominent classes of organic compounds. Among them, bicyclo[2.1.0]pentene ("housene") derivatives represent a highly challenging and very attractive class. Although organic housenes have been known for more than five decades, there are still very few of them containing heavier main group elements.

Bis-?-hydrohexafluoroisobutyrates and bis-pentafluoromethacrylates
Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1989By reacting bis(trifluoromethyl)ketene with ethylene glycol, 1,4-butylene glycol, or hydroquinone the corresponding bis-α-hydrohexafluoroisobutyrates are obtained, which on dehydrofluorination with Et3N·BF3 yield bis-pentafluoromethacrylates.

Bi-convexity and bi-martingales
Israel Journal of Mathematics, 1986Let \(X\subset {\mathbb{R}}^ k\), \(Y\subset {\mathbb{R}}^ m\) be compact convex sets. A martingale \(Z_ n=(X_ n,Y_ n)\), \(n=1,2,...\), with values in \(X\times Y\) is called a bi-martingale if for each n either \(X_ n=X_{n+1}\) or \(Y_ n=Y_{n+1}\) (a.s.).

American Annals of the Deaf, 1993
In the past few years, we have witnessed the introduction of a bilingual-bicultural approach and an increasing skepticism of the value of manually coded English in the education of deaf children. The thrust of bilingual-bicultural programs is emphasis on using American Sign Language as the primary language of instruction.

Sintering of Bi–Tl, Bi–In, Bi–Pb, and Hg–In Contacts
Inorganic Materials, 2004Experimental evidence is presented that the sintering of Bi–Tl, Bi–In, Bi–Pb, and Hg–In contacts is associated with two concurrent processes opposite in thermal effect: the formation of a nonequilibrium liquid phase and nucleation of intermetallic phases.
