Prototropic Rearrangement

Kinetic evidence is presented which strongly suggests that in the diethyl ether solution the aminolysis of p-nitrophenyl isothiocyanate proceeds via a mechanism involving a 1:1-addition intermediate which undergoes catalyzed prototropic rearrangement to the product (Baker-type mechanism).

Heterogeneous Solid

Trimethylborane and anhydrous hydrazine react at 25° in vacuum, yielding a 2:1 adduct, 2(CH3)3B•N2H4, which is stable at or below −78° and evolves trimethylborane slowly at higher temperatures, leaving a stable 1:1 adduct, (CH3)3B•N2H4 (m.p. 42–43°). The thermal decomposition of the latter at 150–160° is complex, producing nitrogen, methane, ammonia, a mixture of butane and the isomeric butenes, and a heterogeneous solid. At 25° diborane displaces trimethylborane from the 1:1 adduct and reacts with it to form 1,1-dimethyldiborane, in addition to hydrogen, methane, and a heterogeneous solid.Trimethylaluminum and hydrazine give a complex reaction in vacuum at 25°, but in diethyl ether solution the product was thought to be (CH3)2AlNHNHAl(CH3)2, which decomposes on being touched.
