The next article includes the description of the rich chemistry of phosphinines, including azaphosphinines. The sixth article deals with synthetic approaches to different types of 1- heterophosphacyclanes, including four-, five-, and six-membered P-heterocycles. The next two articles cover the chemistry of phosphorus containing mac- cycles. The phosphorus containing calixarenes have attracted much attention in recent years due to their various functions such as metal cations binding, catalysis, molecular recogination, and bioactivity. Likewise, other phosphorus-containing macrocycles, cryptands, and dendrimers find various uses in analytical chemistry and biochemistry. We hope to include the following articles in the second volume on phosphorous heterocycles: Diazaphospholes Selected phosphorous heterocycles containing a stereogenic phosphorus Heterophenes carrying phosphorus functional groups as key structures The synthesis and chemistry of the phospholane ring system Synthesis and bioactivity of 2,5-dihydro-1,2-oxaphosphole-2-oxide derivatives Recent developments in the chemistry of N-heterocyclic phosphines. I would be failing in my duty if I do not express my sincere thanks to the people at Springer, particularly Ms. Birgit Kollmar-Thoni and Ms. Ingrid Samide, for coordinating the project with great dedication.
