Abstract:
A simple and convenient method for synthesizing chalcogen-substituted (Ch = S or Se) phosphiranes was achieved through the reaction of a phosphiranide complex with sulfur (or selenium). The presented approach shows a good functional group compatibility. The ring strain and stability of the lone pair of S (or Se) on phosphinidenes enable these phosphiranes to be privileged phosphinidene precursors. The synthetic potentials of these chalcogen-substituted phosphiranes were demonstrated through P-S (Se) bond transfer reactions with various phosphinidene trapping reagents.

Preparation of Alkynes: Dehydrohalogenation
Alkynes can be prepared by dehydrohalogenation of vicinal or geminal dihalides in the presence of a strong base like sodium amide in liquid ammonia. The reaction proceeds with the loss of two equivalents of hydrogen halide (HX) via two successive E2 elimination reactions.

Preparation of 1° Amines: Azide Synthesis
Azide ions act as good nucleophiles and react with unhindered alkyl halides to form alkyl azides. Alkyl azides do not participate in further nucleophilic substitution reactions, thereby eliminating the chances of polyalkylated products. Alkyl azides are reduced by hydride-based reducing agents, like lithium aluminum...
