ABSTRACT OF THE DISCLOSURE Iodopropargyl derivatives of formula: IC === C.CH2.OR [wherein R represents an alkanoyl group (which may be unsubstituted or have one or more halogen, cyano, substituted or unsubstituted .alpha.-phenoxy or phenyl substituents) an alkenoyl group, (optionally phenyl-substituted), a substituted or unsubstituted alkoxycarbonyl group, a cylcoalkanoyl group, a substituted or unsubstituted benzoyl group, a substituted or unsubstituted phenoxycarbonyl group, a substituted or unsubstituted benzyloxycarbonyl group, a heterocyclic carbonyl group, an alkylsulphonyl group, a substituted or unsubstituted benzenesulphonyl group, a naphthyloxycarbonyl group, an iodopropargyloxycarbonyl group, a subtstituted or unsub- stituted cycloalkoxycarbonyl group, a heterocyclic methoxycarbonyl group, a 3-pyridyloxycarbonyl group (which may be unsubstituted or have one or more halogen substituents) or an alkenyloxycarbonyl group] are, except where R represents an acetyl or an unsubstituted benzoyl group, new compounds and are useful for the preservation of a variety of organic materials, including the protection of these materials against fungal or insect attack. The derivatives may be prepared by reacting 3-hydroxy-1-iodo-1-propyne with a compound of formula RX (in which R is as defined above and X represents a halogen atom) or, where R in the desired compound contains an oxy- carbonyl group, reacting the 3-hydroxy-1-iodo-1-propyne with phos- gene and then reacting the product with an appropriate hydroxy- containing compound.
