Bijunctive Vectoplexes

X-Y For the simplest bijimctive case X-Y (e.g. H-Br, I-F, etc.), vector Vv is based on atoms X,Y and is directed from the atom of higher priority to lower (55a, Y X Sequence Rule). 

For all of the above bijimctive cases, the Vy s are tangent to the loop and are therefore classified as either Va or v.

These designations are independent of the nature of the ligogenic process hence, the vectorial permutations shown apply equally well for (1,1)-, (1,2)-, and (2,2)- ligogenic processes. However, the two vectors here belong to a common plane (considered to be the reference plane). Molecular examples of the above-mentioned interacting bijunctive vectoplexes are shown in Figure 13.10.

We will now examine molecular vectogeruc simplexes - molecular vectoplexes - and define vector Vy for various monojunctive and bijunctive molecular vectoplexes encountered in orgaruc transformations.
