mation of the ( Z ) isomer supports the assumption that in compound 13 (and probably also in 12) the substituents at the noncoordinated C=C double bond are arranged cis. The rhodium-containing product of the reaction of 8 or 13 with acetic acid is the chelate complex 17,[\*] which can be reconverted
o)-Halo-~-nitropropane and -butane are cyclized with a base to form cyclic nitronates as labile 1,3-dipoles. They can be trapped by a variety of monosubstituted ethenes to give 3-(2hydroxyethyl)isoxazolines or perhydroisoxazolo[2,3-b]o-oxazines depending upon the ring size of nitronates. The latter
