For earlier data on B2H6, see Boron Compounds 3rd Suppl. Vol. 1, 1987, pp. 49/58, Boron Compounds 2nd Suppl. Vol. 1,1983, p. 41/5, and Boron Compounds 1 st Suppl. Vol. 1, 1980, pp. 70/4. The more recent emphasis in diborane(6) chemistry has been on theoretical studies of this small molecule, and also in the analysis of spectral data. 

This treatment continues that in Boron Compounds 2nd Suppl. Vol. 1, 1983, Section 2.3.4, pp. 59/68, and that in Boron Compounds 3rd Suppl. Vol. 1, 1987, Section 2.4.3, pp. 64/70. The parent system B2H4 continues to attract the attention of theoretical chemists due to its simplicity and its inherent electron deficiency. Derivatives of B2H4 are more readily available now, and the known chemistry of such species is expanding. An interesting development is that the pyrolysis of some cyclic diborane(4) derivatives proceeds with the retention of the boron-boron bond.
