Having reached the age of 65 years, B. F., born in 1933, has retired from teaching duties in September 1998, and from supervising laboratory work in August 1999. Since then he is writing accounts of his former research group’s investigations. He is still interested in organic chemistry.

Research Interests

Playing the Ring Game

Game, a universal form of recreation generally including any activity engaged in for diversion or amusement, and often establishing a situation that involves a contest or rivalry.
[Encyclopædia Britannica, Micropædia, 15th Edition, 1985, Vol 5, p. 105]


Odd things are interesting!

The chemistry of odd-membered rings is full of surprises

(In chemistry, a cyclic array of atoms connected with strong chemical bonds is called a ring)


My first game in chemistry as a single player: Thermal decomposition of trimethylbicyclo[3.1.0]-2-hexen-6-ylammonium hydroxide, Föhlisch, B. Chemische Berichte 97, 88 (1964); Chemical Abstracts 60:6765e. [B. Föhlisch, Die thermische Zersetzung des Trimethyl-Δ2-bicyclo-[3.1.0]-hexenyl-(6)-ammonium-hydroxyds].
