Bronsted acids catalyze the addition of enolizable ss-keto esters to α,ss-unsaturated aldehydes leading to substituted 2H-pyrans in good yields under mild conditions via a formal [3+3] cycloaddition.

Synthesis and properties of dibenzo(d,f)-1,3,2-dioxaphosphorepines of general formula X: O,S Y: viz.OH, SH, Cl R = 2.2'-biphenylylen are reported.The compounds with Y = OH or SH, which may be also named 2.2'-biphenylylenposphoric acids, form metal complexes in which, depending on the type of donor atom (S and /or O), the acid anion acts as a chelating or bridging ligand.
