Abstract:
The sponge Haliclona lunisimilis from Point Loma, California, contained six known chlorinated acetylenes, previously isolated from the dorid nudibranch Diaulula sandiegensis, and three new metabolites, (1Z,3Z)-1-chlorohexadeca-1,3-diene-5,7-diyne-14-ol, (1Z,3E,9Z)-15-acetoxy-1-chlorohexadeca-5,7-diyne-1,3,9-triene, and (1Z,3E)-14-acetoxy-1-chlorohexadeca-1,3-diene-5,7-diyne. The structures of the new compounds were elucidated by interpretation of spectroscopic data. The relationship between the sponge metabolites and the nudibranch metabolites is discussed.

Alkyl Halides
Alkyl halides are halogen-substituted alkanes wherein one or more hydrogen atoms of an alkane is replaced by a halogen atom such as fluorine, chlorine, bromine, or iodine. The carbon atom in an alkyl halide is bonded to the halogen atom, which is sp3-hybridized and exhibits a tetrahedral shape.
Unlike alkyl halides, compounds in which a halogen atom is bonded to an sp2 -hybridized carbon atom of a carbon-carbon double bond (C=C) are called vinyl halides. Whereas aryl...

Acid Halides to Carboxylic Acids: Hydrolysis
As shown below, the mechanism involves a nucleophilic attack by water at the carbonyl carbon to form a tetrahedral intermediate. This is followed by the reformation of the carbon–oxygen π bond along with the departure of a halide ion. A final proton transfer step yields carboxylic acid...
Preparation of Acid Anhydrides
The carboxylate ion acts as a nucleophile that attacks the carbonyl carbon of the acid chloride to form a tetrahedral intermediate. Subsequently, the re-formation of the carbonyl group with the loss of the chloride ion as a leaving group leads to the formation of an acid...
