In organic chemistry, Wittig reaction has attracted both immense interest and controversies among synthetic chemists. It continues to generate contentious issues especially where lithium salt-free reactions are involved. Much of these controversies arise from the original Wittig proposal that the reaction progresses via oxaphosphetane, an idea that was vehemently opposed almost immediately . The topic has received several excellent reviews concerning reaction mechanisms [2, 3]. Mutual consensus among researchers is that all Wittig reactions share a common experimental effect for all phosphonium-based ylide reactions. Similarly, selectivity is consistent for cis-oxaphosphetane together with its derivative products such aserythro-β-hydroxyphosphonium and Z-alkene salt in reactions where aldehydes bearing a heteroatom on the β-position as a substituent are involved. This effect usually operates for both aliphatic aldehydes and benzaldehydes, while in the absence of a substituent heteroatom they do not operate .
