   The synthesis commences with cyclopropanation of 1,1-bis(chloromethyl)ethylene, [4] according to the following scheme: Scheme 1. Synthesis of [1.1.1]propellane. Synthesis begins with conversion of the 1,3-di-carboxylic acid of bicyclo[1.1.1]pentane 1 in a Hunsdiecker reaction to the corresponding dibromide 2 followed by a coupling reaction with ...

   where ν is the frequency of the wave, λ is the wavelength, ω = 2πν is the angular frequency of the wave, and v p is the phase velocity of the wave. The dependence of the wavenumber on the frequency (or more commonly the frequency on the wavenumber) is known as a dispersion relation.

   a the wave amplitude of each frequency component in metres, k 1 and k 2 the wave number of each wave component, in radians per metre, and; ω 1 and ω 2 the angular frequency of each wave component, in radians per second. Both ω 1 and k 1, as well as ω 2 and k 2, have to satisfy the dispersion relation:

   N 2 O 3 is called nitrogen sesquioxide (sesqui-means 1 + 1 ⁄ 2). The main oxide of phosphorus is called phosphorus pentaoxide. It should actually be diphosphorus pentaoxide, but it is assumed that there are two phosphorus atoms (P 2 O 5), as they are needed in order to balance the oxidation numbers of the five oxygen atoms.
