3 ROH PCl 3 3 RCl P(OH) 3 3 ROH PBr 3 3 RBr P(OH) 3 ROH PCl 5 RCl POCl 3 HCl PI 3 has to be generated in situ via reaction of iodine and phosphorous Eg CH 3 (CH 2) 14 CH 2OH P/I 2 CH 3 (CH 2) 14 CH 2I This type of reaction does not work well for tertiary alcohols, and also does not lead to rearranged productsAnswer (1 of 3) I'm putting the answer forward See mechanisms in Chemistry are to explain the phenomenas observed experimentally and hence, at times, you might feel that some steps are forceful but they are at place for explaining experimental results and carrying the Actually, while it s true that PCl5 is commonly used to convert the OH group of an alcohol or carboxylic acid to Cl, it also undergoes a reaction with aldehydes and ketones at low temperature (usually use 0 degrees C when writing it on paper), converting RCOR to RCCl2R (ketone to geminal dichloroalkane) and RCHO to RCHCl2 (aldehyde to geminal dichloroalkane)
