CAS 1720-38-3: 1,9-Decadiyne

1,9-Decadiyne is a monolayer that has been synthesized from the coupling of two phenylacetylene molecules. This molecule has a molecular weight of 204. The interpunctella and pteleifolia species are the only known natural sources of 1,9-decadiyne. These species were bioassayed for antifungal activity against a number of fungi, including Aspergillus niger and Candida albicans. The optical properties of 1,9-decadiyne have been characterized using UV-visible spectroscopy and found to be similar to those of eugenol. Molecular modeling studies have shown that 1,9-decadiyne copolymerizes with polystyrene in an alternating fashion. Pharmacokinetic properties have been studied in rats and show that it is absorbed through the skin and metabolized by esterases in the liver. Gel permeation chromatography results show that there is a large amount

One-step synthesis of carbametacyclophane 3 from 1,9-decadiyne and diethyl acetylenedicarboxylate is described. The use of 1,9-decadiyne as a nucleophile led only to the monoalkynylation product, a selectivity that would be difficult to achieve with a catalytic in situ metalation process. 1,9-decadiyne reacts with iodobenzene (excess) to afford the bis-Sonogashira coupling product in excellent yield. 1,9-Decadiyne was dihydrated and gave 2,9-decanedione in 92% yield.This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
