2 Allyl sulfides, sulfonates, halides, phosphonates, silanes 

With allyl transfer agents (e.g. 11 X=CHo, A=CH2 such as allyl halides. 

Some typical transfer constants for allyl sulfides are given in Table 6.7, The values of C for these reagents are less dependent on the particular monomer than those for halocarbons (Table 6.2) or thiol transfer agents (Table 6.4). The low transfer constant of 32 demonstrates the importance of the activating group Z cf 11).

Allyl sulfonates (35,36) show analogous behavior, Transfer constants are reported in Table 6.8. Other eompounds with weak A-R bonds cf. II) that have the capacity to act as transfer agents are listed in fable 6,9, Allyl bromides 43a, 44, and 45a give predominantly chain transfer whereas, the chlorides e.g. 45b)
