2,2-[60]Fullerenoalkanoyl chlorides (1a−d) were easily and securely prepared from the corresponding 2,2-[60]fullerenoalkanoic acids (2a−d) by the reaction with thionyl chloride in an unusual mixed solvent, CH2Cl2/dioxane. The characterization of 1a−d by 1H and 13C NMR, FT-IR, and MALDI-TOF-MASS was conducted for the first time. The 2,2-[60]fullerenoalkanoyl chlorides thus obtained were readily converted
2-Imino-imidazolidine derivatives of the formula ##STR1## wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are as hereinafter set forth, and pharmaceutically acceptable acid addition salts thereof, are described. The 2-imino-imidazolidine derivatives are useful in the treatment of hypertension.

Disclosed are a range of protected organoboronic acid reagents useful in the modular assembly of complex organic compounds. The reactivities of the protected organoboronic acid reagents may be varied predictably by changes to the number and identities of their substituents. Also disclosed are methods of using the protected organoboronic acid reagents in the synthesis of organic compounds.
