Article Synopsis
- Direct unequal C-H bond difunctionalization of phosphorylated diamantane was achieved efficiently using phosphonates.
- Creating functionalized phosphonates through reduction leads to new types of diamantane phosphines, including primary and secondary ones.
- The stability of the primary diamantyl phosphines in air is notably higher than that of other similar compounds, supported by computational analysis of their molecular structures.
We present an effective sequence for the preparation of phosphonic acid derivatives of the diamondoids diamantane, triamantane, [121]tetramantane, and [1(2,3)4]pentamantane. The reactions of the corresponding diamondoid hydroxy derivatives with PCl3 in sulfuric or trifluoroacetic acid give mono- as well as didichlorophosphorylated diamondoids in high preparative yields.

- Diamondoids are tiny, diamond-like hydrocarbons with unique properties like negative electron affinity, making them useful for high-tech applications like electron-beam lithography and microscopy.
- This study shows that attaching diamantane phosphonic dichloride to tungsten/tungsten oxide surfaces creates a stable bond that withstands higher temperatures compared to traditional methods using gold.
- The findings indicate that these stable diamondoid monolayers can maintain their desirable characteristics even at elevated temperatures, suggesting their potential for use in advanced micro/nano electromechanical systems (MEMS/NEMS).
The antimalarial drug FR900098 was prepared from diethyl allylphosphonate involving the nitroso-ene reaction with nitrosocarbonyl methane as the key step followed by hydrogenation and dealkylation. The utilization of dibenzyl allylphosphonate as the starting compound allows one-step hydrogenation with dealkylation, which simplifies the preparative scheme further.
